Adsorption Kinetics and Isotherms Study of Cadmium Ions from Aqueous Solution on Tailings of Steel Slag

Abstract:

This article explores the operating conditions of the removal of cadmium ions from wastewater by tailings of steel slag and investigates the effect of stirring rate, initial concentration of cadmium, particle size of tailings and pH value of aqueous on removal efficiency. The results show that: under proper conditions, the removal rate of cadmium ions from water on tailings of steel slag can be up to above 99.9%. The adsorption kinetics follows the pseudo-second-order kinetics equation and the adsorption isotherm conforms to the Langmuir model.
