Role of Calotropis Procera for Removal of Ni(II) Ion from Waste Water

Nirmal Choudhary, Kanchandeep Chaudhary, Bhanupriya Mordhiya and Kailash Daga

The present work deals with the removal of Ni(II) ion using activated charcoal prepared from the stem of Calotropis procera. The Ni2+ adsorption was found to be dependent on adsorbent dose, initial concentration, pH and contact time. The removal of Ni ion is higher at lower conc. and gradually decreases as the concentration increases. The pH 6 was the most suitable for removal and removal of Ni(II) ion increases with the increase in the absorbent dose.
