Absorption approach for recovery and removal of Cd (II) from aqueous solution using coir dust

摘要

Removal of cadmium, Cd (II) from aqueous solution was studied using Coir Dust, Carboxylated Toluene and Sulphonated Toluene Resins. The experiment was performed as a function of solute concentration and contact time. The effect of Cd (II) on adsorption was then examined. The effect of resins on adsorption showed that the quantity of metals adsorbed from solution rise with increase in time and attain equilibrium at 60mins for Coir Dust and Sulphonated Toluene Resins and at 90mins for Carboxylated Toluene Resine. Different isotherms were employed to study the effect of time and concentration. The data showed that Coir Dust is efficient in the recovery and removal of Cd (II) from aqueous solutions.
