氢化物发生-原子荧光光谱法测定铜阳极泥中的砷

Determination of Arsenic in Copper Anodic Slimes by Hydride Generation-Atomic Fluorescence Spectrometry

用氢化物发生-原子荧光光谱法测定铜阳极泥中的砷量,研究了仪器测量条件、氢化物发生条件、共存元素等因素对测定结果的影响。选择了最佳测定条件,砷的测定范围为0.50%—5.00%,加标回收率在98.3%—108.0%之间,相对标准偏差小于4%,能满足测定的要求。

Arsenic in copper anodic slimes was determined by hydride generation-atomic fluorescence spectrometry.The effects of operating conditions,hydride generated conditions and coexisting elements were studied.The method is applicable in a range of 0.50%—5.00%.The recovery of standard addition is in the range of 98.3%—108.0% and the relative standard deviation is less than 4%.
