摘　　要：通过一系列除杂过程,从人造金红石母液中提取出纯度较高的氯化亚铁晶体,并采用双水解的方法制得了氧化铁红;对制得的氧化铁红的形貌及其中金属元素含量进行了分析。结果表明:采用该方法制得的氧化铁红的杂质金属元素含量少,颗粒均匀规整,色泽鲜明;对氧化铁红进行包膜处理,可解决其颗粒局部团聚的问题。Through a series of process for impurity removal, higher-purity ferrous chloride crystal was extracted from synthetic futile mother liquor, and iron oxide red was prepared by double hydrolysis. The morphology and metal element content of the prepared iron oxide red was analyzed. The results showed that the impurity metal element content of the iron oxide red prepared by this method was low; particles were uniform and regular, and had bright color; iron oxide red was coated, thus solving the problem of local agglomeration of particle.
