Adsorptive removal of cadmium (II) from wastewater using activated carbon synthesized from stem of Khat ().

Introduction: Cadmium is among the most hazardous heavy metals, posing the greatest risk to human beings and the environment. Adsorption with activated carbon prepared from agricultural waste is the most effective way to remove cadmium (II) from wastewater. In this study, activated carbon prepared from the stem of Khat ( plant was used for the removal of cadmium (II) from wastewater.
