| Abstract: | The flow injection analysis (FIA) of vitamin C in pharmaceutical tabletsis discussed in this paper. This method is based on the oxidation-reductionreaction between vitamin C and t,10-ferriin (Ⅲ) with the formation of ahighly colored compound and requires that absorbance values be read at510mn. The correlation coefficient of the standard curve is 0.9999. The co-efficients of variation from the analytical results of two batche samples are0.24% and 0.19% and the mean recovery is 99.8%. No difference is observedbetween the FIA and the phamacopocia method except that the formermethod is easier and less time-taking than the latter. |
