Synthesis and Characterization of Modified Cellulose and Their Use for Removal of Heavy Metal Ions from Aqueous Solution
Journal Title: Saudi Journal of Medical and Pharmaceutical Sciences - Year 2018, Vol 4, Issue 6
Abstract
Abstract:In present study an attempt has been made to prepare new polymers depending on Cellulose viscous pulps to study the adsorption activity for removal of heavy metal ions from single aqueous solution. Barley and Corn Straw have been used for the extraction of crude pulps. Grafted viscous pulp has been prepared by using acrylamide as a monomer and benzoyl peroxide as an initiator in different ratios at different conditions of temperature and time. Epichlorohydrin was used as cross linking agent under the optimum conditions of grafting for the preparation of Grafted cross linked viscous pulps. The grafting percentage, grafting efficiency percentage and swelling behavior of new polymers were also studied. The structures of these compounds were established by using FTIR and elemental analysis. For the removal of chromium and nickel ions from an aqueous single metal solution the graft pulp copolymer and grafted crosslink viscous pulps were used as adsorbents. The results of the present study revealed that the ratio of pulp to monomer 1:4g/g, ratio of cellulose to initiator 1: 0.3g/g, grafting time 3 hours and grafting temperature 70 ◦C showed the optimum conditions of grafting. All the polymers synthesized in the present study showed the activity to remove heavy metal ions from an aqueous solution and the maximum activity have been shown when the cross linking agent was used in the synthesis. Keywords: straw, pulp, copolymerization, acrylamide, hydrolysis, crosslinking, metal ions uptake.
