摘要
本文对葡萄糖还原铬鞣液三种方案的浸酸／铬鞣循环的各次废液的组成进行了研究。结果表明：各方案的废液循环四或五次后，其硫酸根和氯离子浓度及比重均趋向平衡，趋向平衡的速度和平衡浓度决定于各自的工艺条件。
Three schemes of the recycling of glucose-reduced chrone tan liquor in pick-ling-tanning system are studied. The results show that the sulfate ion and cholride ion in theused chrome tan liquor is showing a tendency to equlibrium after four or five runs in pickling- tanning system.
