| 摘 要： | Cotton cellulose reacted with epichlorohydrin under the catalytic action of HClO_4 and H_2O 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 Cu~(2+)-complexing capacity and good mechanical strength, and can be used under pH12.
