Abstract
This study explores the use of modified kaolin clay as an eco-friendly, cost-effective material for wastewater treatment, focusing on the removal of dyestuffs. Clay samples were characterized using X-ray fluorescence, X-ray diffraction, and atomic absorption spectrophotometry, revealing that kaolinite and quartz were the dominant minerals. The modification of kaolin clay enhanced its sorption properties, particularly for heavy metals like Cd2+, Cu2+, Fe2+, and Pb2+, with higher sorption capacities due to the presence of iron and aluminum oxides. Factors such as contact time, pH, and initial metal ion concentration influenced the adsorption process, with the Langmuir isotherm model providing the best fit. These findings highlight the potential of kaolin clay for applications in water purification, soil improvement, and pollution control, particularly in regions with limited access to advanced treatment technologies. Future research should focus on optimizing modification processes and assessing the long-term effectiveness of kaolin clay in various environmental settings
