摘要
本文研究了磺基水杨酸（ＳＳＡ）光度法测定硅藻土类助滤剂中Ｆｅ２Ｏ３，并对测试条件、测定方法进行了研究．方法比较简单，也可用于其它粘土矿物中Ｆｅ２Ｏ３的测定．
This peper has rasearched the SSA photometric method for determination Of Fe2O3 in diatom filter-aid,inchiding its test conditions and its determinaton method. This method is a little simple. So it is also applicable for the determination of Fe2O3 in silicious soil.
