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。

Abstract: The conventional determination method for iron oxide content in iron oxide pigments will pro-duce 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 or-ange or titanium trichloride instead of mercury chloride for removing of residual SnCL,. This method provided a satisfactory result, and no mercury - contianing waste water discharge.
