人造金红石母液制备含铝聚合氯化铁研究

Preparation of Aluminum-Containing Polyferric Chloride from Artificial Rutile Acid Waste Liquid

本研究以盐酸浸出法制人造金红石副产酸性废液为主要原料,经氧化、聚合、熟化制备出无机高分子复合混凝剂—含铝的聚合氯化铁(PFC),分析制备PFC的优化条件。在室温条件下,100 mL人造金红石浸出母液通入4.6 g氯气,氧化10 min后获得含铝聚合氯化铁,采用除浊方式对制备的产品进行表征,考察该混凝剂对生活污水的净化效果。

In this study, the artificial rutile by-product acid waste liquid was prepared by hydrochloric acid leaching method as the main raw material, and the inorganic polymer composite coagu-lant—aluminum-containing polyferric chloride (PFC) was prepared by oxidation, polymerization and ripening. The optimized conditions for the preparation of PFC were analyzed. At room tem-perature, 100 mL of synthetic rutile leaching waste liquid introduced 4.6 g of chlorine gas, and after 10 minutes oxidation, aluminum-containing polyferric chloride was obtained. The prepared product was characterized by turbidity removal method, and the purification effect of the coagulant on domestic sewage was investigated.
