Abstract
In food chain system, heavy metal contamination in water is a major environmental problem. Copper (Cu2+) is one of the heavy metals frequently found in wastewater and can harm aquatic ecosystems and human health in high concentrations. Therefore, to reduce the amount of Cu2+ in water, efficient treatment techniques are needed. One potential alternative is the use of waste based adsorbents, such as Polysulfide Sorbent (PSS) synthesized from used cooking oil and sulfur through an inverse vulcanization process. This study aims to analyze the characteristics and performance of PSS in reducing Cu²⁺ concentrations in artificial wastewater using a higher PSS mass than previous studies. The research method was carried out in batches using a jar test apparatus with an adsorbent mass of 7 g/L at pH 6. Variations used included initial Cu²⁺ concentrations of 2, 3, 4, and 5 mg/L and contact times of 40, 80, 120, and 160 minutes. The adsorption test for Cu²⁺ concentration was carried out using Atomic Adsorption Spectrophotometry (AAS), while the adsorbent characteristics were tested using SEM-EDX. The adsorption data were then analyzed using One-Way ANOVA analysis, Langmuir and Freundlich isotherm models, and the adsorption kinetics rate. Through this study, the most effective Cu2+ removal results, based on the principles of ANOVA statistical significance and material usage efficiency, were obtained at 76%, at the 120th minute with an initial Cu2+ concentration of 4 mg/L. Increasing the contact time up to the 160th minute was ineffective and could cause the PSS to experience a new equilibrium (re-equilibration). The treatment of variations in the initial Cu2+ concentration did not show any differences in results from each other due to the small range and the PSS had experienced saturation earlier. The results of the characteristic test with SEM-EDX showed that PSS has a high sulfur content of 85.4 wt% which functions as an active site in binding Cu²⁺ ions, and after adsorption there is a Cu content of 1.702 wt% on the adsorbent surface, which indicates the success of the adsorption process. With a maximum adsorption capacity of only 0.554 mg/g, neither the Langmuir nor the Freundlich isotherm models are representative, as the R² values for both are far from 1. The zero order kinetic rate model is the most representative rate model. This indicates that the conditions of the experimental adsorption system determine the performance of the PSS. Based on these findings, Polysulfide Sorbent (PSS), derived from sulphur and used cooking oil, has the potential to serve as an alternative adsorbent for reducing Cu²⁺ concentrations, provided that the appropriate research variables are selected. Keywords: adsorption, Cu²⁺, polysulfide sorbent, used cooking oil, heavy metals.
