沉淀法去除工业级硫酸铝中铁的研究进展

The Research Progress of Iron Removing from Industrial Grade Aluminum Sulfate by Precipitation

文章对目前硫酸铝除铁技术中最常用方法之一的沉淀法进行研究,并结合国内专利申请和论文对沉淀法中的高锰酸钾/二氧化锰法、铁氰化钾与亚铁氰化钾法、黄钾铁矾/黄铵铁矾法及有机络合法进行机理分析和进展研究。

One of the common methods which is precipitation for removing iron from aluminum sulfate is researched. And the method of potassium permanganate/manganese dioxide, the method of potassium hexacyanoferrate（Ⅲ） and potassium hexacyanoferrate（Ⅱ）, the method of jarosite/ammonioiarosite and the method of complexation are analysed about the mechanics and researched of the progress combining with patents and papers.
