Abstract: Anew method is presented for spectrophotometric determination of ascorbyl palmitate with silica- molybdenum heteropoly bine.The method is hased on the reaction of molybdenum heteropoly acid with ascorbyl pnlmitate.Optimum experimental conditions have been established.The apparent absorptivity is at 720nm.The de- terminatiom range is 0.25 ~ 2.0mg/50ml.the recovery is 99.4% ~ 100.4%,and the variation coelhcient is 0.43%.
