Development of a method for cadmium ion removal from the water using nano γ-alumina/β-cyclodextrin

Cadmium is one of the heavy metals, which is harmful to humans and animals. The toxicity of this metal in the body has caused many studies to remove it in water and soil. Because according to WHO, the maximum concentration of cadmium in drinking water is 3 μg/L. In this study, trace amount of Cd ion...
