In solubility and partitioning process of benzoic acid, the various factors are involved such as temperature, solute-solvent interaction and dissociation of acid into ionic state in taking solvents. Here, we reported the benzoic acid (solute) solubility in gram/100gram of solvent in different pH benzene-buffer solutions which are analyzed by using of titration method and partition study of these acid into solvents like water and benzene layer by shake-flask acid-base titration method, at room temperature (25°C) for 24 hours. In titrimetric estimation the solute benzoic acid solubility and their partition in between of water and in different pH buffer solutions as in medium of acidic, neutral and basic, a phenolphthalein indicator have been used well. The solvents and benzene-buffer solutions having different pH 4.0, 7.0 and 9.0 is titrated against as 0.01, 0.05 and 0.1N NaOH solutions by using phenolphthalein as indicator, where the end point show a pink color for each reading. Concentration of benzoic acid into water and solvent benzene layers is being calculated as by applying the equation of normality determination and distribution coefficient as from Nernst distribution law equation.

Millions of people worldwide are adversely affected by Arsenic continuing exposure, so providing arsenic-free consumption of water is an immense task for the researchers. The chemistry, content of arsenic-contaminated water as well as adsorption play a big role in arsenic elimination. The mechanism of adsorption technology's elimination of As (V) from the water was simply presented as the elements that govern various adsorption paths. The effects of a variety of adsorbents on As (V) elimination from aquatic were explored in the present research, which classified the materials used as adsorbents based on physical, chemical, and biological processes. When choosing an adsorbent, adsorption capability is an important factor to consider. As a result, developing As (V) elimination from aquatic adsorption strategies includes developing environmentally acceptable materials with effectual adsorption abilities, refining the preparation and alteration procedures of recent adsorbents, and boosting renewal effectiveness. After choosing a particular adsorbent for As (V) elimination from water, regional features of arsenic-polluted water, applied viability of the adsorption process, besides suitable environments of respectively material must be extensively reviewed and analyzed. The current study gives an outline of the adsorption technique to remove arsenic from wastewater, as well as the adsorption capacity of various adsorbents.

Despite increasing human activities, such as agriculture, little information is available on the status of trace metals contamination in rivers in developing countries including Côte d’Ivoire (West Africa). The aim of this study was study chemical fractions of Cu, Pb, Zn, and Ni, to identify mobility, sources and to evaluate ecological risks of traces metal in sediment of N’zi River using modified BCR sequential extraction procedure. The results showed that all metal were dominated by residual fractions. Labile fractions of Pb accounted for 0.0 – 68% of total contents indicating significant anthropogenic sources for Pb, while for Cu, Ni and Zn results suggesting natural sources. The potential mobility of the metals manifested following order: Ni > Zn > Cu > Pb. Risk assessment code indicated low to medium risk for Pb and low risk for other metals in the sediments. Cluster analysis (CA) and Matrix correlation were used to detect the relationship between the studied sampling sites and to see if some of the parameters interrelated with each trace metal concentration in exchangeable fraction. Results indicated high anthropogenic contamination at stations near to urban and agricultural areas.

Water pollution has great impact on environmental degradation. Release of untreated wastewater containing toxic metal ions into natural waters is a threat to aquatic ecosystem and is attributed to affect the health of living things. Date nut carbon was analysed as an adsorbent for extracting Cr(VI) ions from wastewater using batch method. Investigations were done by varying the pH from 1 to 6, carbon dose from 0.1 g to 0.5 g and equilibration time from 1 to 24 hours. Cr(VI) removal of 93% occurred at an optimal pH of 2, carbon dose of 0.3 g/100mL, and equilibration time of 3 hours. The adsorption of Cr(VI) on Date nut carbon followed first order kinetics. The kinetic process of Cr(VI) adsorption onto Date nut carbon was tested by applying first order kinetics.

The assessments of the seasonal metal pollution, as well as the subsequent likely ecological and health risks, of the open waters from the lagoon area II of Ébrié system were the subject of this study. For this purpose, the seasonal mean of As, Cd, Cr, Cu, Fe, Hg, Mn, Ni, Pb, and Zn contents of these waters determined over the period from June 2020 to May 2021 were used. The water quality guidelines SEQ-Eau (version 2) and NQE DCE-UE 2018/240 were used to assess the seasonal ecological quality of these waters. As for the seasonal biota health risks, they have been assessed with the water quality guidelines of NYSDEC, US-EPA and SAVEX. Those concerning to Human health risks, they were with WQSSW of Port Gamble S'Klallam tribe. The results showed an important ecological degradation of these waters in all seasons. This has been due to As, Cd, Hg, Ni, and Pb. The likely biota health risks are also significant in all seasons, due to As, Hg, Ni, and Pb. As for the likely Human health risks, they are also important in all seasons. They are due to As, Hg, and Ni over the study period.

Pd-Catalyzed hydrogenation process has been developed to synthesize tetrahydrocurcumin from synthetic curcumin. Use of diphenyl sulphide as catalyst poison is crucial for lowering the activity of the catalyst and thus reduces impurity formation. The process avoids column chromatography to achieve good quality tetrahydrocurcumin in cost effective manner. All the prepared compounds are characterized by FT-IR, 1H NMR, mass and HPLC techniques.

Co(II), Ni(II) and Cu(II) complexes of N and O donor ligand derived from ,5-dinitrosalicylicacid and thiosemicarbazide, the spectroscopy techniques like UV-Visible, FT-IR, NMR, mass spectrometry, p-XRD and SEM analysis were used to structurally characterize the metal complexes. From the analytical and spectral evidence, the square planar and octahedral geometry has been proposed to metal (II) complexes. In addition to this computational density functional theory (DFT) using B3LYP/6-31Gþ(d, p)/Lanl2dz(f) method in the ground state was performed, the calculations were done to confirm the geometry of the complexes and also HOMO-LUMO excitation energies levels were also calculated. Additionally, MTT test was used to perform cytotoxic assays on selected MCF-7 (estrogen receptor-positive human breast cancer cells) and HeLa (human cervical cancer cell line) cell lines. The antibacterial test was performed via the disc plate method against Escherichia coli and Staphylococcus aureus, and was further supported by molecular docking interactions using protein receptor SEC2 (PDB code: 1STE) in Staphylococcus aureus.

Clays containing materials of regular structure are the most common inorganic sorbents for water purification in nature. Sorbents belonging to the type of expandable structural stratum minerals include montmorillonite and vermiculite, which form the basis of bentonite clays. Bentonites are clays which compose mainly of minerals belonging to the group of montmorillonite and sometimes called stonesoap. Navbahor alkaline bentonite deposit is located in Navbahr district of Navoi region of Uzbekistan Republic. The current proven reserves of the deposit are more than 7142.6 thousand tons. Montmorillonite is mainly the most effective adsorbent for various compounds and water purification. The surface area of montmorillonite is 450 m2/g, and vermiculite is 450-500 m2/g [1].

Liquid-liquid extraction is a chemical unit operation that utilizes the difference in solubility or distribution ratio of target components in two immiscible solvents to achieve separation, extraction or purification. There are many factors that affect the extraction efficiency, and it is difficult to quickly optimize the process using traditional methods. Artificial neural network is a system structure composed of multiple artificial neuron models, with functions such as self-learning, associative storage and fault tolerance. It can be used for optimization or control of multi-variable complex systems, and has been successfully applied to the extraction process of various products. optimization. This paper discusses the basic situation of artificial neural network, and analyzes the research progress of extraction process optimization based on neural network.
