This study investigated the applicability of natural Egyptian Na‐montmorillonite (Na‐MMT) to remove Pb2+, Cd2+ and Ni2+ under acidic conditions that mimic industrial wastewater acidity. Cation exchange capacity of Na‐MMT was found 91 meq/100 g and the specific surface area 42 m2 g−1. The adsorbent was characterized using X‐ray fluorescence, scanning electron micrograph that showed significant morphological...
