利用高浓度有机酸废水作还原剂制备铬鞣剂

Preparation of Chrome Tanning Agent with High Concentration Waste Organic Acid as Reducing Agent

利用香料厂排放的高浓度有机酸废水部分代替葡萄糖作还原剂和蒙囿剂,制备铬鞣剂,并对制备出的鞣剂的理化性能及鞣制性能,进行综合分析。结果表明,制得的铬鞣剂和商品铬粉质量相当,证明利用高浓度有机酸废水部分代替葡萄糖制备铬鞣剂,是完全可行的。

The chrome tanning agent was prepared with some wastewater produced from perfume factories contained high concentration organic acid as reducing agent and masking agent by which part of glucose was replaced. Comprehensive analysis was made on the physicochemical and tanning performance of the produced tanning agent. It shows that the produced tanning agent is competitive with that available in the market. So the method mentioned above is a practical and feasible one.
