英文摘要：

The charge-transfer reaction between ceftriaxone sodium and p-benzoquinone has been studied spectrophotometrically. The optimization of experimental conditions on the formation of charge transfer complex was performed. At room temperature, ceftriaxone sodium reacts with p-benzoquinone in borax buffer solution and forms a 1 ： 2 complex with apparentmolar absorptivity of 1.73×10^4 L · mo1-^1 · cm^-1 at 606.0 nm, Beer＇s Law is obeyed in the range of 2- 24υg/mL of ceftriaxone sodium with a correlation coefficient of 0. 9998. The proposed method was applied to the determination of ceftriaxone sodium for injection and satisfactory results have been obtained. The recovery is 98. 64 %- 100. 7 % and the relative standard deviation is 1.03%.
