Abstract
The aim of this research is to craft a material that effectively curbs the higher level of heavy metals and salinity in brine from desalination plants. Through thorough experimentation, an optimized form of Halloysite Nanoclay was achieved, which was further enhanced with 8-hydroxyquinoline for increased metal removal efficiency. The enhanced nanoclay's adsorption capabilities were carefully fine-tuned, displaying a type III adsorption isotherm and a significant surface area (72.8 m² g–1). The modified Halloysite nanoclay demonstrates improved efficiency in removing metal ions, achieving rates of 79.12 % for Zn, 83.33 % for Fe, 81.18 % for Ni, and 79.81 % for Cu. Notably, this advanced material proved its prowess in purifying heavy metals. The prepared material displayed noteworthy recycling capacity, substantiated through a series of experiments. This study highlights the effectiveness of using modified Halloysite nanoclay to treat desalination plant brine sustainably, opening avenues for further research and practical applications in this area.
