Abstract

Pollution of wastewater from the fuel and energy complex, petrochemical and metallurgical industries with heavy metals is one of the urgent environmental problems of modern industry. Arsenic, copper zinc, etc. its ions are highly toxic, accumulate in bottom sediments and disrupt biosphere processes. Developing effective wastewater treatment technologies is a priority within the framework of sustainable development. Heavy metals (As, Pb, Cu, Zn) with water pollution pose a serious threat to ecosystems and human health. The adsorption process is one of the widely applied engineering methods for the efficient and environmentally safe removal of these pollutants. The effective sorption conditions of heavy metal ions were determined using natural and modified adsorbents, following that continuous optimization of the process was carried out. The effect of initial metal concentration, pH, adsorbent dose and contact time on adsorption efficiency has been studied. The optimal conditions of the technological process have been determined by means of mathematical modeling. The results showed that under optimal conditions (pH = 6.7, dose = 1.8 g/L, contact time = 120 min), the adsorption efficiency was higher than 96%. The process obeys the pseudo-secondary kinetic model and aligns well with the Langmuir isotherm, indicating monomolecular absorption. The results of the study allow preventing the pollution of the ecosystem with the heavy metals, as well as formulating sustainable engineering approaches for environmentally safe treatment of industrial wastewater. The developed model can be applied in designing environmentally friendly adsorber systems.
