摘要
本文通过酸溶和过氧化钠碱熔对照试验,采用酸溶分解试样;以加入和不加入掩蔽剂A进行对照,选择溶剂A作为六价铬的掩蔽剂,无需分离,硫酸亚铁铵滴定钒量,该方法操作简便、快速、准确。
In this paper, through acid and alkali fusion of Sodium peroxide contrast controlled trials, the use of acid-soluble sample decomposition, to join and not to join the A masking agent for the contrast control, choice of solvent A as the masking agent for hexavalent chromium, without separated from ferrous sulfate Ammonium vanadium titration, the method was simple, rapid and accurate.
