摘要
本文提出了原子吸收法直接分析固体样品中的Pb。无需对样品进行化学处理,将固体研磨过筛后均匀悬浮于琼脂溶胶中,选择最佳的仪器工作条件,由自动进样器取样于石墨炉中测定。该方法准确易行,工作效率高。
A new AAS method for the determination of lead in samples is described.A solid sample is suspended in a agar sol in stead of being disolved, and injected into a graphite furnace by automatic sampler to determine directly.Optimum conditions for the determination of lead are discussed.The method is accurate, convenient and rapid.
