“…Adsorption often has advantages over other processes due to its low start-up and installation costs, high selectivity, practicality, flexibility, ease of operation, low environmental risk, resistance to toxic components and significant potential for the removal of hazardous, unsafe contaminants [33,34]. Up until now, different materials have been used for the removal of Cd 2+ , such as brewery yeast [35], barley husks [36], brewed tea waste [33], nanocomposites [37,38], eggshell [39,40], sunflower [41], peanut shell [42], sugarcane bagasse [43], different clay materials [44][45][46][47][48][49], and minerals like montmorillonite, kaolinite, illite, zeolite, diatomite, vermiculite [50].…”
