REMOVAL OF NICKEL IONS USING TEA AND COFFEE WASTES AS LOW-COST ADSORBENTS: A GREEN APPROACH

MONIKA KUMARI AND SANJAY KUMAR SHARMA

Abstract

Ni(II) adsorption on tea and coffee wastes was examined by using batch adsorption. The reason to choose these adsorbent is their availability and low-cost nature. For finding the adsorption efficiency of adsorbents variable conditions have been used such as temperature, pH, initial metalion concentration, adsorbent dose, and contact time. Functional group detection was carried by FTIR and the final concentration was determined by AAS. Experimental results revealed the maximum metal ion removal by tea and coffee wastes was 64.9% and 70.2% at optimum conditions.
