This article investigates the adsorption efficiency of polysulfide sorbents synthesized from local raw materials in selectively removing heavy metal ions- specifically Fe2+, Cu2+, Zn2+ and Pb2+- from industrial wastewater obtained from oil and gas processing facilities. The study tested PSK-1, PSK-2, and SMED-8 grade sorbents, evaluating their adsorption capacity, selectivity, and reusability. Analytical assessments were conducted using UV–Vis spectrophotometry and atomic absorption spectroscopy (AAS). The experimental results demonstrated that the SMED-8 sorbent exhibited high efficiency and long-term operational stability. This development holds significant promise for the advancement of environmentally friendly and economically feasible sorption technologies.
