Abstract: (26 Views)
This study explores the modification of shrimp shell waste (SSW) using NaOH and H₂O₂ to enhance its adsorption efficiency for Cd(II) and Ni(II) removal from industrial wastewater. At pptimized conditions (pH 6 for Cd, pH 5 for Ni), maximum adsorption capacities of 33.62 mg/g and 13.70 mg/g were achieved, respectively. SEM and FT-IR confirmed structural changes improving adsorption performance. Langmuir isotherm model indicated monolayer adsorption. The findings highlight chitin’s potential as a cost-effective, sustainable adsorbent for wastewater treatment.
