摘要
方法采用硝酸——盐酸混合试剂热分解，氢化物发生原子荧光法测定土壤中砷［1］，砷的相关系数为0.9996，方法检出限为0．01mg／kg，相对标准偏差在3．1％～5．5％之间，加标回收率为95％-105％之间，精密度和准确度试验结果满意。
This method uses nitric acid--muriatic acid extender to clear up and HG--AFs method to mensurate As in Soil,Relative coefficients： 0.9996 （for As）.The limit of thismethod is 0.01mg/kg,the relative standard deviations are 3.1%-5.5%,the rate of callback are 95%-105%.The obtained precision and accuracy were satisfied.
