Hexavalent chromium, one of the heavy metal pollutants in water, harms ecological environment and human health. In this work, an aniline-p-phenylenediamine copolymer has been prepared by chemical oxidative polymerization to remove hexavalent chromium (Cr(VI)) from wastewater. The results show that when initial Cr(VI) concentration is 1.5 mg·L−1, removal percentage (RP%) could reach 94.84% after 180 s treatment. RP% increases with dosage copolymers decreases increase concentration. Additionally, reaches a maximum 97.70% pH value 1.0. kinetics follows pseudo-first-order reaction model. X-ray photoelectron spectroscopy (XPS) demonstrate mechanism redox reaction. positive ΔH° negative ΔG° affirm process endothermic, thermodynamically achievable, spontaneous.

In today’s ongoing rapid urban expansion, deforestation and climate changes can be observed mainly as unbalanced rain occurrence during the year, long seasons without any at all unordinary high temperatures. These adverse affect underground water levels availability of surface water. addition, quite a significant proportion drinking is used for non-drinking purposes. With several EU countries increasingly suffering from droughts, reusing quaternary treated wastewater help address scarcity. At European level, Regulation 2020/741 Parliament Council 25 May 2020 on minimum requirements reuse was adopted. This regulation foresees use recycled agricultural irrigation. article provides an overview various processes, such filtration, coagulation, adsorption, ozonation, advanced oxidation processes disinfection, treatment in order to remove micropollutants achieve reuse. According literature, most effective method with acceptable financial costs combination membrane filtration (UF or NF) UV disinfection. are relatively well known commercially available. also helps researchers identify key themes concepts, evaluate strengths weaknesses previous studies determine areas where further research needed.
