Abstract

PURPOSE: To obtain an improved dialysis membrane made of regenerated cellulose of a cuprammonium process causing no yellowing of physiological salt soln. in preparation of dialysis by specifying reducing groups at below specific values.
CONSTITUTION: The copper value of cellulose is regulated to ≤0.2, more preferably ≤0.1. Here, the copper value denotes the (g) number of the copper reduced from the cupric copper in an alkaline soln. to cuprous copper by 100g dry cellulose.
