摘要
本实验联合应用高性能空心阴极灯、缝式石英管、高效雾化器乙炔－空气火焰原子吸收法，采用节流脉冲进样来测定工业硅中铅，使铅的灵敏度改善３１倍，同时克服了Ｆｅ、Ａｌ等原子化过程中形成的氧化物吸附石英管壁对实验的影响。此法简便、快速。
The combined use of high performance hollow cathode lamp,slotted quarty tube,high effeciency nebulizer and throttle pulse injection sampling in flame AAS can improve the analytical sensitivity up to 31 times for the determination of trace lead in industrial silicon .At the same time ,It can eliminate the adsorption effects on slotted quarts tube in the presence of Fe,Al,etc.This method is quick and simple.
