Comparative Study of Adsorption Kinetics of Ni (Ii) Using China Clay and Flyash as Adsorbents

Dr. P. P. Vishwakarma

Abstract: The present study was aimed to compare the study of adsorption kinetics and percentage removal of Ni (II) using China clay and Fly ash as adsorbents. The effect of contact time, adsorbent dosage, pH of system and initial concentration on the kinetics of adsorption was studied. The rate constants for the removal of Ni (II) with both adsorbents for varying metal ion concentration showed it to be a first order kinetics. Adsorption data was fitted well into Freundlich adsorption isotherm.
