摘要

The presence of dyes in aquatic effluents is highly visible, undesirable, carcinogenic to human beings and toxic to living organisms. EDTAD modified cellulose extracted from Pennisetum purpureum was studied as an adsorbent for the removal of cationic dyes from spiked waste-water. Shimadzu Fourier Transform Infrared spectrophotometer, was used to analyze functional groups of cellulose and EDTAD modified cellulose. The characteristic peaks at 1260 cm~(-1), 1634 cm~(-1), 1058 cm~(-1), and 1740 cm~(-1) indicated formation of ester bond linkages associated with the introduction of EDTAD thus successful modification of cellulose. Shimadzu UV-VIS 1800 series determined the degree of dye concentration. Optimum adsorption was determined by varying the dosage, pH, contact time, and the initial concentration of the dyes.
