Preparation and characterization of magnetic kaolinite nanocomposite as methylene blue adsorbent in aqueous solution / Izzan Salwana Izman

Wastewater treatment of untreated dye effluent from industries is challenging due to requirement of adsorbent that is cost-effective, highly efficient, robust, and feasible to operate. In this study, magnetic kaolinite nanocomposite (MKN) derived from Malaysia’s natural kaolinite clay mineral is pro...
