采用王水消解土壤样品，用氢化物发生原子荧光光谱法同时测定土壤中砷锑的含量。研究并优化了载气及屏蔽气的流量，硼氢化钾的浓度，灯电流等试验条件。砷的质量浓度在0～500μg · L -1范围内，锑的质量浓度在0～250μg · L -1范围内与荧光强度呈线性关系。应用此方法分析了3份土壤样品，以标准加入法做回收率试验，回收率在98．0％～108.0％之间。
採用王水消解土壤樣品，用氫化物髮生原子熒光光譜法同時測定土壤中砷銻的含量。研究併優化瞭載氣及屏蔽氣的流量，硼氫化鉀的濃度，燈電流等試驗條件。砷的質量濃度在0～500μg · L -1範圍內，銻的質量濃度在0～250μg · L -1範圍內與熒光彊度呈線性關繫。應用此方法分析瞭3份土壤樣品，以標準加入法做迴收率試驗，迴收率在98．0％～108.0％之間。

HG -AFS was applied to the determinations of arsenic in soil with aqua regia assisted sample di-gestion . The flow rates of carrier gas and shielded gas , concentration of potassium borohydride , electrical current of lamp were studied and optimized . Linear relationship between the fluorescence intensity and mass concentration of Arsenic was found in the range of 500 μg.L -1 . The proposed method was applied to the analysis of 3 soil samples , and values of recovery found by standard addition method were in range of 98 .0% to 108 .0% .
