摘　　要：常规测定氧化铁颜料中氧化铁含量时产生难以处置完全的含汞废水,污染环境。本文介绍了对有汞测定加以改进的无汞测定法,以甲基橙或三氯化钛代替氯化汞去除残留氯化亚锡。无汞法不仅效果令人满意,而且没有含汞废水,有利于环境保护。The conventional determination method for iron oxide content in iron oxide pigments will produce a mercury - containing waste water which is difficult to be handled, causing environment pollution. This article has described a new mercury -free determination method for iron oxide, which used methyl orange or titanium trichloride instead of mercury chloride for removing of residual SnCl2. This method provided a satisfactory result, and no mercury -contianing waste water discharge.
