DEVELOPMENT OF A HIGH-EFFICIENCY ADSORBENT FROM E-WASTE AND ALUMINOSILICATE-BASED MATERIALS FOR THE REMOVAL OF TOXIC HEAVY METAL IONS FROM WASTEWATER

摘要

An impregnated and activated ion exchange material prepared by a process is provided that includes: impregnating an ion exchange precursor material, wherein impregnation of the ion exchange precursor material includes reacting the ion exchange precursor material with an impregnator solution, thereby increasing the surface area and the hydrophilicity of the ion exchange precursor material; activating the impregnated ion exchange precursor material to increase the porosity of the impregnated ion exchange precursor material, wherein the ion exchange precursor material comprises at least one of nonmetallic printed (NMP) circuit board, amorphous aluminosilicate, or mixtures thereof. In other aspects, a method for fabricating an ion exchanger and a method for removing heavy metal ions from a solution are provided.
