heavy metal removal by modified cellulose nano fibers(mcnf)

In this work, at the first step hardwood pulp was modified by the maleic anhydride; and then electrospinning of modified solution was carried out under different voltages. at last obtained fibres was washed with water and aqueous 70% (w/w) ethanol and prepared to use as a nano absorbent. the synthesized absorbent was characterized by sem and ftir. the degree of substitution of modification reaction is 1-1.8 by titration method. the affection of other parameters like ph, contact time and temperature on removal was studied. the results show that the modified cnf has a great capacity of absorption for hg(ii).
