摘要
采用原子荧光光谱法测定水处理剂聚氯化铝中砷。实验结果表明,线性关系良好(在标准曲线0.0～30.0μg/L 内,平均相关系数γ为0.9996),精密度较好(相对标准偏差为1.76%～2.66%),准确度、灵敏度较高(加标回收率为103.5%～107.7%,最低检出限为0.08μg/L),是测定水处理剂聚氯化铝中砷的较好方法。
With atomic fluorescence spectrometetic determination of Arsenic in Water treatment chemical- Poly aluminium chloride was carried out,The results obtained showed that linearity is well （the average correlate is 0.9996 in standard cure 0.0-30.0μg/L）.The precision is better（the relative standard deflectivity is 1.76%-2.66%）.The accuracy and sensitivity are higher （the recovery is 103.5%-107.7%,detection limit is 0.08μ g/L）.It is better method for the determination of Arsenic in Water treatment chemical-poly aluminium chloride.
