Abstract
25Oct 2016 A COMPARATIVE STUDY FOR THE REMOVAL OF COPPER AND ZINC IONS USING SOME TREATED CARBON R. S. Salama , H. A. Kiwaan and M. R. Mostafa. Department of Chemistry, Faculty of Science, Damietta University
Highlights
% hydrous zirconium oxide on the textural and adsorptive properties was studied
The characterization of prepared carbons is performed by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR) and nitrogen adsorption at 77K
A comparison between the two images showed that activation with H3PO4 results in more homogeneous surface with large number of pores while sample ZnCl2 activation (ZC) has a considerable number of disordered random of shallow cavities
Summary
Received: 10 August 2016 Final Accepted: 23 September 2016 Published: October 2016 ions from their aqueous solutions onto activated carbons obtained from date stone by chemical activated method using H3PO4 and ZnCl2. The resulting material was separated by filtration, washed for several times with 2% NH4Cl solution and with hot distilled water till free from chloride ion and dried at 110 C0 for 24 hours This sample was referred to as OCZ. In contrast ZnCl2 and H3PO4 activated carbons as well as the sample loaded with 10 weight % hydrous zirconium oxide (OCZ) exhibit isotherms of type I with hysteresis loop of H4 [25]. Table (1) summarizes the textural parameters of the investigated carbons as derived from the adsorption isotherms and BET equation as well as from αs plots (not illustrated) [30] It is evident from table (1) that comparable areas and total pore volumes for each carbon sample are obtained using BET equation and αs method.
