| Abstract: | The method for the determination of the content of ceftiofur sodium for injection was established by ultraviolet spectrophotometry.The maximum absorption wavelength of ceftiofur sodium was 292nm,and there was a good linear relationship between absorption and concentration of ceftiofur sodium in the range of 2.5—22.5μg/mL.The regression equation was A = 0.0547x+0.0102 with R~2 of 0.9999(n = 9).The method is simple,quick and reliable,and that can be applied to the determination of the content of ceftiofur sodium for injection. |
