- W2371881504 abstract "The chromogenic reaction between cefaclor and ninhydrin was investigated by spectrophotometry.The experimental optimum conditions were confirmed.A simple and rapid method for determination of cefaclor was developed.The apparent molar absorptivity of complex was 4.53×10~3L ? mol~(-1) ? cm~(-1) at wavelength of 565 nm,when reaction of cefaclor and ninhydrin in aqueous solution(pH = 5.4) completed under boiling water bath for 1h.Beer's Law was obeyed in the range of 10—90mg ? L~(-1) for cefaclor mass concentration with correlation coefficient of 0.9993.The relative standard deviation was 1.16%(n= 6).The recovery was over 99.0%.The proposed method is applied to determination of content of cefaclor in preparation,and results conform to pharmacopeia method." @default.
