| 摘 要： | 目前我国环境地表水和污水中铅的测定方法,仍然主要采用直接火焰和石墨炉原子吸收法。但直接火焰原子吸收法测铅的检出限不能满足一般地表水分析的要求,而石墨炉原子吸收分光光度计造价比较昂贵。本文建立了氢化物发生-原子荧光法测定地表水和污水中铅的方法,检测范围宽,检出限低,完全可以作为地表水和污水中铅的检测方法。

| Abstract: | Until now the flame atomic absorption spectrophotometry(FAAS)and graphite furnace atomic absorption spectrophotormetry(GFAAS)are the main methods for the determination of lead in water.But the detection limit of FAAS can't meet the requirement of surface water analysis,and GFAAS is expensive.This paper presents a hydrogenate generation-atomic absorption fluorescence spectrometric method for the determination of lead in surface water and polluted water.The method has wide measurement range and low detection ... |
