Title: Adsorption of Chromium (Vi) And Lead (Ii) Using Adsorbents (Sesame Cake, Corn Leaves And Banana Husk)
Author: Alameen, Abdallateef Ali Mohammed
Abstract: Three low cost adsorbents (sesame cake, corn leaves, and banana husk) were tested for the removal of chromium (VI) and lead (II) from contaminated water. All experiments were carried out in batch process at normal pH and temperature. Effects of adsorbent dose and contact time were investigated on removal of chromium (VI) and lead (II). Generally removal efficiency was found to increase with increase in adsorbent dose and contact time. It was found that sesame cake based adsorbent demonstrated better chromium (96.03%)and lead(84.43%) removal efficiency as compared to corn leaves (88.96%) for Cr(VI) and (85.01%) for Lead (II)) and banana husk (85.75% ) for Cr(VI) and (92.69%) for Lead (II). In addition the surface properties of the developed adsorbents were characterized using FTIR. Analysis of FTIR shows that the hydroxyl, carbonyl, aliphatic, ethers, alcohol, phenol and carboxylic groups were present on the surface of adsorbents. The adsorption kinetics for both metals are well described by first order model on sesame cake and banana husk and by second order model on corn leaves. On the basis of present studies it can be concluded that the abundant of effects (concentration, PH, temperature).Moreover, These adsorbents can be used as raw source of adsorbent materials as they have the great potential for the removal of chromium (VI) and lead (II) from the waste water
