头孢磺啶(cefsulodin,CFS)与克拉维酸(CA)合用,可使抗菌活性增强.本文推荐用零交叉一阶导数分光光度法测定二元混合物中CFS和CA的含量.方法快速,不需分离,且准确度和重现性好.CFS和CA的线性范围是2.0～56.0和2.0～28.0μgml~(-1).
The combination of cefsulodin (CFS) and clavulanic acid (CA) can enhance the antibacterial activity.In this paper, the determination of CFS and CA in binary mixtures by zero cross first derivative spectrophotometry is recommended. Separated and with good accuracy and reproducibility.CFS and CA linear range of 2.0 ~ 56.0 and 2.0 ~ 28.0μgml ~ (-1).
