用王水浸取样品中的砷、汞，用预还原剂（硫脲+抗坏血酸）还原，在用原子荧光测定溶液中砷汞元素含量，本法通过选择王水，并在水浴条件下分解样品，极大的提高了样品分解速度，缩短样品检测周期，利用原子荧光分光光度计测定，避免了冷原子吸收的不稳定性，与其他方法比较，本法操作简单，检测周期短，检测结果更加准确可靠。

Through the method of acid soluble, the sample is dissolved in hydrochloric acid, conditions, most of the iron reduction with stannous chloride, using titanium trichloride reduction two valent iron all, with two sodium diphenylamine sulfonate as indicator, titration with potassium dichromate standard solution of iron content, this method by choosing a mixture of phosphoric acid and sulfuric acid, and the sample is decomposed at high temperature, greatly improves the sample decomposition rate, shorten the sample testing cycle, using titanium trichloride reduction, avoiding the bichloride of mercury pollution, and human injury, compared with other methods, this method has the advantages of simple operation, short detection period, the detection result is more accurate and reliable.
