文摘

Raw corn silk as novel adsorbent for copper and zinc has been investigated. Adsorption process of metal is favorable and occurs under monolayer surface. The involvement of complexation and ion – exchange binding mechanisms is confirmed. Adsorption process is feasible, spontaneous and endothermic. Adsorbent can be efficiently regenerated and reused.
