摘　　要：运用氢化物发生 -原子荧光光谱法 ,经过各种条件试验 ,建立测定地面水与废水中痕量铅的分析方法 ,在 0 .0 0 0 4～ 0 .0 5 mg/ L 线性范围内 ,铅的最低检出限为 0 .4μg/ L,标液变异系数 <2 % ,样品变异系数 <8% ,样品回收率 1 0 0 %～1 0 5 %。A method was developed for the determination of trace Pb by HG AFS The trace Pb soluble Pb is existed in drain off water from heating station Instrumental working parameters and experimental conditions are studied Under the optimum conditions selected the detection limit is 0 4μg/L Dynamic linear range is 0 0004～0 05mg/L The relative standard deviations are <2% and 8% The recovery of known samples is 100%～105%
