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.
