Adsorption Equilibrium of Pb2+ Removal from Aqueous Solutions Using Spent Batteries
Abstract
The main goals of water treatment at adequate quantity and quality are to improve the living con- ditions, reduce poverty among the people and to ensure human and economic development. This paper presents a report on removal of lead using a household waste (spent batteries). Spent batteries were collected, sectioned; carbon rods (cathode) were removed washed with distilled water and characterized. Carbon rods were ground into powder and sieved into different particle sizes. Properties of the powdered carbon rods (PCR) were studied. Ad- sorption properties of PCR were studied using synthetic lead solutions, typical raw water and domestic institutional wastewater with a particular attention to its equilibrium isotherms.
The study revealed that PCR has pores, it adsorbed Pb2+ from aqueous solutions (synthetic lead solution, raw water and domestic institutional wastewater). Equilibrium isotherms for Pb2+ adsorption from aqueous solutions can be grouped into two based on the values of correlation coef cient (R2) as follows: equilibrium isotherms with R2> 0.95 (Langmuir, Freundlich, Sips, Langmuir- Freundlich, Crombie-Quilty and McLoughin,Temkin,Koble- Corrigan, Fritz and Schlunder models) and R2< 0.95 (Hasley and Redlich- Peterson). Applicability of the process to lead ion removal from aqueous solutions showed that PCR can be used as an adsorbent for Pb2+ ions removal from aqueous solutions.
It was concluded that PCR is a good adsorbent for Pb2+ ions removal from aqueous solutions.
