Preparation and application of grafted Holarrhena antidycentrica fiber as cation exchanger for adsorption of dye from aqueous solution

Present investigation deals with the removal of methylene blue from waste water using Holarrhena antidycentrica cellulose based cation-exchanger. Initially hydroxyethylmethacrylate was graft copolymerized onto H. antidycentrica cellulose and was converted into cation exchanger through phosphorylation. On optimization of different reaction parameters maximum graft yield obtained was 632.0%. Characterization of the synthesized samples was done by FTIR, SEM–EDX and XRD techniques. Thermal stability of samples was investigated through TGA/DTA/DTG techniques. Dye removal study was done in terms of contact time, initial concentration of dye and dose of cation exchanger. Ion-exchanger was found to be highly efficient for removal of methylene blue with maximum removal of 85%. The results showed that ion exchanger could be employed as effective and low cost eco-friendly material for removal of dyes and color from aqueous solution.
