| 摘 要： | 采用氢化物发生-银盐分光光度法对中草药中溶解态砷的含量进行了测定。结果表明，砷标准曲线的回归方程为C=1．4474 A-0．0087，r=0．99，在0～0．4μg/mL的范围内，线性关系良好。对5种样品进行了回收实验，回收率为92．4％-102．6％，相对标准偏差为1．26％-2．43％。该法简单、快速、灵敏、准确。

| Abstract: | A method was proposed for the determination of arsenic by hydride generation - sik, er salt spectrophotometry. The result shows that regression equation of arsenic standard curve is C = 1. 447 4 A - 0. 008 7, r =0.99, the detection limit of theproposed method was found to be 0 - 0.4 μg/mL. The method was successfully applied to the determination of arsenicin five kinds of Chinese herbs with a recovery range of 92.4% - 102.6% , and the RSDs were in the range of 1.26% - 2.43%. The method is simple, rapid, sensitive and accurate. |
