Cephalexin was found to be polarographically reducible after hydrolysis in an acidic medium, producing two polarographic waves. Both waves were diffusion controlled. The concentration-diffusion plot method was used for the analysis of cephalexin in capsules.
头孢氨苄在酸性介质中水解后被发现可极谱还原,产生两个极谱波。两个波均受扩散控制。采用浓度-扩散图法对胶囊中的头孢氨苄进行分析。
