Optimum Conditions for Removal of Some Heavy Metal Ions from Aqueous Solutions Using Cellulose Acetate
Authors
Abstract
This study describes the ability of cellulose acetate to remove heavy metals (Hg+1, Cd+2, and Pb+2) from aqueous solutions. The extraction operation of these ions was carried out by using the column tech. Different particles size of cellulose acetate (38>µm, 38-53µm,53-106µm), differentretention times (1 min, 5 min, and 10 min), and various pH(2, 6.7, and 10) to select the optimum conditions for the recovery of these ions were used.Flame and flameless atomic absorption spectroscopy were used to determine the concentration of these ions.The obtained results reveal that the percent adsorption for removal of most ions at (pH = 6.7, particle size less than 38 µm, and 3 min retention time) was approximately 90%.
