چکیده مقاله

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).‎
