| Abstract: | stability of phosphomolybdate blue reduced with sodium fluoride-stannous chloride for determination of phosphoim in iron and steel by spectrophotometry has been studied.The regularity of absorbance change along with time gone on was observed.The factors effecting on the regularity and the mechanism of absorbance change have been investigated in detail. The improved method is proposed in this paper. |
