Abstract

Chemical modification of cellulose was successfully carried out using different amounts of sodium tripolyphosphate. Cellulose was extracted using 2% sodium hydroxide and 10% H2O2 solution from the stem of Calotropis procera, the stem was dried after which the lignin content was removed. Incorporation of sodium tripolyphosphate (STTP) on the cellulose matrix, showed an increase in thickness and size of the cellulose microfibrils. The absorption band appeared at 1287 cm?1 in the Fourier transform infrared spectroscopy (FTIR), and is attributed to P=O stretching of the modified cellulose. Scanning electron microscopy (SEM) and X-ray diffraction analysis (XRD) analyses were used to characterize the modified cellulose. The results of adsorption for the following heavy metals were found to be 71.43 mg/g, 41.84 mg/g for Pb2+, Cu2+ respectively. The adsorption equilibriums data satisfactorily fitted Langmuir isotherm equation better than Freundlich isotherm. The study indicates that the modified cellulose could be used as adsorbent for the removal of Pb2+ and Cu2+ ions from aqueous solution.
