摘要
对氢化物-原子荧光法测定水处理剂聚合氯化铝和硫酸铝中铅的测定介质、测定条件及干扰元素进行了探讨,拟定了简便、快速、准确测定两种水处理剂中微量铅的方法.在测定条件下,方法的线性范围为0～50ng·ml^(-1),检出限为0.4ng·ml^(-1),回收率在90%～110%之间.
A method for the HG-AAS determination of microamounts of lead in poly aluminium chloride and aluminium sulfate used as water scavengine agents is presented in this paper. The optimum conditions for the determination and the tolerance of interfering elements were studied. A simple and rapid method is proposed. Under the optimum condition, a linear relationship holds between the absorbaces and concentrations of lead in the range 0 ?0ng ?ml^(-1). A detection limit of 0. 4ng ?ml^(-1) and a recovery between 90%~110% were attained.
