草浆造纸黑液中胶体成分的测定方法及其对黑液碱回收的影响

Determination and Effect of Colloid Composition on the Recovery of Caustic Soda in Straw Pulp Papermaking Black Solution

根据草浆造纸黑液组成的特殊性，研究了草浆黑液中液体成分的测定方法，进行了样品分析和回收率试验．取得了较满意的结果。在些基础上讨论了草浆黑液中胶体成分对于黑液碱回收过程的影响。

The effect of colloid composition on the recovery of caustic soda in straw pulp papermaking black solution is described. On the basis of the characteristics of the black solution, a method for the determination of colloid composition is studied. The samples were analyzed. The recovery and relative standard deviation were 98. 8 % ~ 100. 4 % and 0. 51 % ~ 1. 04 %.
