| Abstract: | It is studied in paper that hydrogenate generation technique is used in the elec trothermic quartz tube-AAS determination of micromounts of lead in environmenta l water sample The optimum conditions for the determination and th e elimination's of interfering elements were discussed Under the optimum conditi on, a linear relationship holds between absorbency and concentrations of lead in the range of 0~25ng/ml. A limit of detection of 0 48ng/ml, a recovery of 95%~116% and a RSD of less than 2 5% were obtained |
