本文用一阶导数差示脉冲极谱法（FDDPP）对链霉素、青霉素G、土霉素，用二阶导数差示脉冲极谱法（SDDPP）对氯霉素、卡那霉素、核糖霉素进行了定量研究。链霉素、青霉素G、土霉素、氯霉素、卡那霉素、核糖霉素分别在200～700μg·ml-1，35～210μg·ml-1，10～60μg·ml-1，32～192μg·ml-1，150～900μg·ml-1，80～480μg·ml-1的范围内与导数差示脉冲极谱峰幅值呈极为显著的线性关系（P＜0.01）。链霉素、青霉素G、土霉素、氯霉素、卡那霉素、核糖霉素的峰电位、检测限分别为0.100V，5.6×10-8mol·L-1，－1.400V，8．0×10-9mol·L-1，－1.536V，6.9×10-7mol.L-1，－0.060V，60×10-9mol·L-1，－0.370V，4.6×10-8mol·L-1，和-0.105V，7．2×109mol·L-1。方法简便、快速、灵敏，结果准确。
In this paper, the first derivative differential pulse polarography (FDDPP) of streptomycin, penicillin G, oxytetracycline, using second derivative differential pulse polarography (SDDPP) of chloramphenicol, kanamycin, ribose Mice were studied quantitatively. Streptomycin, penicillin G, oxytetracycline, chloramphenicol, kanamycin and ribosamycin were respectively in the range of 200 ~ 700μg · ml-1, 35 ~ 210μg · ml-1 and 10 ~ 60μg · ml-1, ~ 192μg · ml-1, 150 ~ 900μg · ml-1,80 ~ 480μg · ml-1 and the derivative differential pulse polarographic peak amplitude showed a very significant linear relationship (P <0.01). The detection limits of streptomycin, penicillin G, oxytetracycline, chloramphenicol, kanamycin and ribosamycin were 0.100V, 5.6 × 10-8mol·L-1 and -1.400V, respectively. 0 × 10-9mol·L-1, -1.536V, 6.9 × 10-7mol.L-1, -0.060V, 60 × 10-9mol·L-1, -0.370V, 4.6 × 10-8mol·L- 1, and -0.105V, 7.2 × 109mol·L-1. The method is simple, rapid, sensitive and accurate.
