Abstract
The present work involved Ni(lI) removal by a non-conventional
adsorbent, Kaolinite clay. The effect of contact time, adsorbent
dosage, pH and initial concentration of the metal ion on the kinetics
of adsorption was studied. It was observed that Ni(ll) removal
increases with increasing contact time and becomes constant after
5 h. As the adsorbent dosage is increased from 2 to 4 g percentage
reduction increase continuously. The effect of pH on the removal
of Ni(II) showed that percentage adsorption increases with increasing
pH up to 9. The adsorption data was fitted will in Freundlich
isotherm, Langmuir isotherm, Langergran's equation and also
Weber Morris equation.
