Drugs are essential pollutants in the environment due to their resistant structure, and their high consumption in treating humans and animals. The entry of antibiotics as hospital waste into aquatic environments is considered one of the critical environmental means due to their high stability. The design and synthesis of Fe 2 O 3 /Ag/Zn as a new structure of Fe 2 O 3 were reported, because of its resis- tance of the structure to air and high temperature, the adsorbent of azithromycin in wastewater was studied. After characterization of Fe 2 O 3 /Ag/Zn by scanning electron microscopy, energy-dis- persive X-ray spectroscopy, mapping, transmission electron microscopy, X-ray diffraction and Fourier-transform infrared spectroscopy. Then, to remove azithromycin, the effect of factors such as pH, the concentration of azithromycin solution, adsorbent dose, time and temperature was evalu-ated using an optimization process. The results showed that the optimal conditions for removing of 96% of azithromycin (10 mg/L) with 1.5 g/L of Fe 2 O 3 /Ag/Zn, pH = 5, and 30 min at room temperature, In other words, the nano absorbent has a good ability to remove azithromycin from water solution, which is very important from environmental aspects.

A novel dual-heated water and power cogeneration system (WPCS), in which photovoltaic/thermal (PV/T) is used for seawater heating and electricity generation, and solar collector is applied for air heating, based on the humidification–dehumidification (HDH) cycle, is proposed. Comprehensive performance of the dual-heated WPCS is obtained, and the parametric analysis, from the pinch enthalpy difference (PED) within the humidifier and solar intensity, are accomplished. It is found the peak gained-output-ratio (GOR), water production and water production cost (WPC) 2.55, 76.32 kg·h –1 and 15.14 $t –1 , with an uneconomical payback period (PBP). The parametric analysis implies a lower PED and higher solar intensity are profitable to raise the water production, while the GOR will decrease instead when the solar intensity rises. Furthermore, it is illustrated a higher PED and solar intensity can reduce the PBP. It is concluded the combined applications of the PV/T and solar collector can result in the advantages, to neutralize the features of the single heated, water-or air-heated HDH systems, HDH desalination methods for raising water production and GOR. However, the impossibility to recover the cost of the dual-heated WPCS within the working lifetime is also discovered, although this is of less importance in areas with water shortages.

This study aims to investigate the simultaneous removal of Methylene Blue (MB), Direct Blue 71 (DB71), and Pb(II) ions, which are frequently found together at high concentrations in different industrial wastewaters, such as textile, paper, leather, paint, and plastic manufacturing waste- waters. The simultaneous removal of Pb(II) ions with MB and DB71 from binary mixtures was investigated by the adsorption method. Magnetic halloysite nanotubes-alginate (MHNTs-ALG) hybrid beads were used to remove these components from the binary adsorption media. For this purpose, a magnetic property was gained to halloysite nanotubes using the “co-precipitation method”. Magnetic halloysite nanotubes (MHNTs) were composited with alginate (ALG) biopoly - mers through the “extrusion dripping method”. The adsorption capacities and efficiency of these synthesized MHNTs-ALG hybrid beads were investigated according to their anionic and cationic pollutant content in binary mixtures, and the synergistic and antagonistic effects of these compo- nents on each other were investigated by comparing them according to single systems. The compatibility with the multi-component Langmuir adsorption model for binary systems was examined using equilibrium adsorption data, and the values of the constants showing the adsorption capacity and affinity were calculated. In binary mixtures of Pb(II)-MB, the maximum amounts of Pb(II) and MB adsorbed per unit adsorbent weight calculated from the multi-component Langmuir model were 248.46 mg/g ( q Pb, m ) and 946.92 mg/g ( q MB, m ), respectively. The maximum adsorption capacities of Pb(II) and Direct Blue 71 from binary systems were determined as 203.14 mg/g ( q Pb, m ) and 118.96 mg/g ( q DB71, m ), respectively. The co-presence of Pb(II) and MB was concluded to cre- ate a synergistic effect compared to the adsorption of Pb(II) ions alone and an antagonistic effect compared to the adsorption of MB alone. The co-presence of Pb(II) and DB71 was observed to form a synergistic effect compared to the individual presence of Pb(II) ions and an antagonistic-synergistic mixed effect compared to the individual presence of DB71.

Pyridine is an important raw material in the pharmaceutical industry. Aminopyridines are key intermediates for the synthesis of important pharmaceutical products. 2-Aminopyridine is used in the production of antibacterial and several antihistamines drugs. Pyridine compounds have harmful effects on the liver, kidneys, immune systems, and reproductive functions, and have potential carcinogenicity. It is very essential to degrade 2-aminopyridines from an aqueous environment on a priority basis. Large-scale application of Fenton/photo-Fenton processes employing ferrous salts Fe 2+ may prove costlier for the complete treatment of contaminated water/wastewater containing such recalcitrant compounds. 100% degradation of 2-aminopyridine (10 mg·L –1 ) by the Fenton process required 180 min out of which 58% degradation was achieved in the first 60 min of the reaction. The pho-to-Fenton oxidation process showed an improved rate of degradation. Parameters like pH, the dosage of hydrogen peroxide, and iron extracted from laterite soil are optimized for the effective degradation and mineralization of 2-aminopyridine in water. Kinetic studies were also conducted using the optimum conditions for 2-aminopyridine degradation and, the pseudo-first-order kinetic equation has been fit up to the reaction time of 30 min. High-performance liquid chromatography analysis was also carried out to confirm the cleavage of the pharmaceutical compound 2-aminopyridine.
