摘要
建立了氢化物-原子荧光法同时测定土壤中砷和汞的方法。在建立的最佳工作条件下，用微波消解处理样品，砷的回收率为90％～110％，汞的回收率为95％～105％，方法的检出限、精密度和准确度均能满足土壤检验的要求，可广泛地应用于各种环境土壤的检测。
Method of mensurating soil Arsenic and Hydraxgyrum simultaneously using microwave digestion hydride-atomic fluorescence spectrometry was setup. Under optimum conditions,the recovery rates of Arsenic and Hydrargyrum could be up to 90 % - 100 % and 95 % - 105 % respectively when samples was digested by microwave. The precision and accuracy accord with the requirement of soil test, which could be widely used in kinds of soil detection.
