| 摘 要： | 本文采用喷流型连续氢化物发生器,氢化物-火焰原子吸收光谱法对岩石、矿物中微量铅的测定条件进行了研究。用铁氰化钾作为铅的氧化剂,草酸为干扰抑制剂,于217.0nm波长,测得铅的特征浓度为0.012μg/ml(1％吸收)。相对标准偏差(对0.6μg/ml Pb)为0.97％。

| Abstract: | A simple and sensitive method for the determination of lead in rock and mineral by hydride generation-flame AAS with a hydride generator of squirt type has been developed. Potassium ferricyanide and oxalic acid are chosen as oxidizing agent of Pb and interference suppressing agent, respectively. The proposed method has been used to determine micro amounts of Pb in rock and mineral. The precision is better than 1%. |
