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).
