Heavy Metals (Cr (VI), Cd (II) and Pb (II)) Ions Removal by Modified Jute: Characterization and Modeling

Abstract

Jute modified has been used for adsorption of Cr (VI), Cd (II) and Pb (II) ions over a range of<br />initial metal ion concentration. Adsorption process is done in batch mode. Adsorption isotherms of<br />the heavy metals on adsorbents prepared were determined and correlated with common isotherm<br />equations. It was found that the Freundlich isotherm is better than Langmuir for explaining the<br />behavior of adsorption. The effect of some parameters such as adsorbent quantity, pH value and<br />temperature were investigated. The enlargement of pH value until 5 and adsorbent quantity<br />increase the adsorption quantity. Whereas exceed of the temperature has the reverse effect.
