研究抗癌药物 8-氮鸟嘌呤的示波极谱分析方法 .在 0 .1 mol/L H2 SO4 底液中 ,8-氮鸟嘌呤于 - 1 .0 3 V产生一灵敏的极谱还原波 ,峰电流与 8-氮鸟嘌呤浓度在 1 .0× 1 0 -8～ 9.0× 1 0 -5mol/L范围内有良好的线性关系 ,检测下限达 9.0× 1 0 -9mol/L,回收率在 95 %～ 1 0 3 %之间 .
To study the oscillopolarographic method for the analysis of 8-azaguanine, an antitumor drug, 8-azaguanine at -0.1 mol / L H2 SO4 produces a sensitive polarographic reduction wave , The peak current and 8-azaguanine concentration in the range of 1.0 × 10 -8 ~ 9.0 × 10 -5 mol / L has a good linear relationship, the detection limit of 9.0 × 10 -9 mol / L, the recovery Between 95% and 103%.
