Numerous scientific and technological developments in wastewater treatment procedures are brought on by the shortage of clean water supplies. Heavy metals' recalcitrance in wastewater has been shown to be a difficult issue. Further, drinking water quality must be at its highest for human health to be at its best; nevertheless, a number of human activities are continuously degrading it, which has an effect on human health either directly or indirectly. Because heavy metals are the primary causes of many chronic illnesses and have a tendency to bio accumulate, they are giving rise to a lot of worries. Technologies from all over the world are being developed to address the demand for clean drinking water. The objective of the current study is to raise awareness of the need to remove dangerous dense metals from various types of wastewater and the application of modified graphene nanocomposite for their adsorption-based removal. Graphene-based nanocomposite materials have been picked for this application due to their large surface area, superior mechanical strength, and reactivity towards polar and nonpolar contaminants for the electrostatic emission of the heavy metal ions arsenic (As)

Extraction and transport of amino acids through a liquid membrane system is an emerging field of supramolecular as well as biomedical science. In this piece of work, series of podands are used with triethylene and tetraethylene glycol chains having benzonitrile (PBT3, PBT4), anthraquinone (PAT3, PAT4) and naphthyl (PNT3,PNT4) end groups. Extraction and transport studies performed with amino acids: glycine, valine and threonine using these receptors. From the results, it is observed that the extraction efficiency of PBT3 and PBT4 is double than PNT3 and PNT4 podands, and also transport ability is double in PAT3, and PAT4. Thus we conclude that the nitrile group-containing podands (PBT3 and PBT4) are better extractants as well as a carrier than PAT3, PAT4, PNT3, PNT4, in which nitrile groups is a key component for molecular recognition of glycine, valine, and threonine, which are further used in the separation of amino acids.

Laurus Tamala leaves extract (LTLE) has been employed as a soft steel corrosion inhibitor in a 1M Hydrochloric acid media. Chemical (weight loss) and electrochemical investigations were carried out to assess the corrosion rate and percentage inhibition efficiency of the extract. The electrochemical polarization results have demonstrated that plant leaves extract functions as a mixed type inhibitor. The stability of the inhibitor is tested at elevated temperatures by weight loss method. The corrosion inhibition mechanism is interpreted through adsorption mechanism, and the LTLE components has obeyed the Langmuir adsorption isotherm for soft steel. The interaction of the components of the extract is assessed through FT-IR technique. The surface morphology, roughness and hydrophobicity in presence and absence of the extract have been characterized through SEM, AFM and water contact angle techniques respectively. The highest inhibitory efficiency is 96.21% for 24 h as recorded by weight loss method. Additionally, the DFT computations has revealed the inhibitor’s adsorption through electron donor-acceptor interactions.

In this article, research has been conducted on obtaining an eco-friendly inhibitor and its application in practice. The source of the green inhibitor is the Salsola oppositifolia plant, from which the method of obtaining the green inhibitor extract is studied. The obtained extract is studied as a green inhibitor in 0.5 M HCl solution for corrosion protection of carbon steel structures. In determining the efficacy of a green inhibitor derived from the Salsola oppositifolia plant, practical experiments have been performed at two different temperatures (298 K and 313 K) and at different concentrations (200 mg/L , 400 mg/L, 600 mg/L, and 1000 mg/L). Adsorption of green inhibitor on steel surface has been studied using Langmuir and Temkin isotherms. The effect of temperature and concentration on the corrosion rate is also studied. The gravimetric method is used to determine the effectiveness of the green inhibitor and it is found that its maximum concentration is 91.86%. The mechanism of action of the steel surface and a post-experimental steel sample are studied by scanning electron microscope analysis. Salsola oppositifolia extract is a good green inhibitor due to the presence of hetero atomic organic compounds in the main component.
