摘要
以２．６－二氯苯醌氯亚胺作显色剂，用电荷转移络合一分光光度法测定头孢氨苄含量。测定波长为５１０ｎｍ，在２～１２ｕｇ／ｍｌ范围内回归方程为Ａ＝０．０５７５ｃ－０．０１ｒ＝０．９９９０平均回收率为９９．３４％（ＲＳＤ＝０．６４％ｎ＝５）方法简便、快速。
A new spectrophotometric method for the determination of ccphalcxin using2,6-dichloroquinoncchlorimide has been developed. The wavelength is 510 um. The regressionequation is A = 0. 0575C- 0.01(r = 0.9990),with the linear rage 2-12 ug/ml. The average recoveryis 99. 34%(RSD= 0.64% n = 5). This method is simple and rapid to give sastisfactory results.
