The adsorption capability of Sponge Iron Plant (SIP) waste was investigated for the removal of Zn metal from aqueous solutions. The objective was to enhance the adsorption efficiency through surface modification with HCl, which increased the BET surface area by 29%. This modification was validated using FTIR and SEM analysis. A comprehensive study was conducted to understand the influence of multiple parameters, including pH, temperature, initial Zn concentration, and adsorbent dosage, utilizing a 24 full factorial design of experiments (DOE). The analysis revealed that while all main effects were statistically significant, their interactions were not. The most significant parameter was found to be pH, with adsorption capacity reaching 128.20 mg/g at pH 8 and 30 °C, based on fitting to the Langmuir model. The data followed a pseudo second-order rate model, indicating a promising potential for SIP waste in effective Zn adsorption. The findings underscore the significance of optimizing adsorption conditions to enhance heavy metal removal from industrial wastewater, addressing environmental concerns associated with heavy metal pollution.
