摘要
基于Ｔｌ（Ⅲ）与碘化物和乙基紫在阿拉伯树胶存在下形成离子缔合物的显色反应，建立了高灵敏分光光度测定铊的分析方法。
Based on the colour reaction of thallium with iodide and ethyl violet in aqueous solution containing surfactant, a highly sensitive spectrophotometric method for determining trace thallium(Ⅲ) has been proposed. The molar absorptivity is 3.07×10 5L·mol -1 ·cm -1 .This method can be applied to the determination of trace thallium (Ⅲ) in water.
