摘要

Cotton cellulose reacted with epichlorohydrin under the catalytic action of HClO4 and H2O to form 3-chloro-2-hydroxypropyl ether with a substitution degree of 0.61. The chlorine-containing product was treated with aliphatic diamines (ethylenediamine

propylenediamine

etc.) to produce nitrogen-containing cellulose which further reacted with humic acid to give black fiberous graft cellulose. This product contains 27—35% humic acid

0.90 meq/g acidic groups

possesses 0.49 meq/g Cu2+-complexing capacity and good mechanical strength

and can be used under pH12.
