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％。 In this paper, jet-type continuous hydride generator, hydride generation-flame atomic absorption spectrometry was used to study the determination of trace lead in rock and mineral. Using potassium ferricyanide as the lead oxidizer and oxalic acid as the interference inhibitor, the characteristic concentration of lead was found to be 0.012 μg / ml (1% absorption) at 217.0 nm wavelength. The relative standard deviation (for 0.6 μg / ml Pb) was 0.97%.
