摘要
用一定量的 Ba2+将铁红(Fe2O3)中的 SO24以 BaSO4形式分离,然后用等离子体光谱法测定余量的Ba2+,从而间接测得SO24的含量.该法操作简便、检测快速,相对标准偏差小于9.0%(n=5),加料回收率93.0%~99.3%.
In this paper, a method is proposed in which a certain amount of Ba2+ is added into a iron oxide red (Fe2O3) solution so that SO2-4 in it is separated in the form of BaSO4, the ex-tra Ba2+ in the solution is then determined by ICP-AES, thus the content of SO2-4 is indirectly determined. The method is simple in operation, fast in detecting, with the relative stan-dard deviation less than 9. 0% (n=5) and the addition recovery of 93. 0%~99. 3%.
