研究了在0.1 mol/L H3PO4介质中,活化剂抗坏血酸的作用下,V(Ⅴ)催化KClO3氧化甲基红褪色的指示反应,由此建立了一种测定痕量V(Ⅱ)的催化动力学光度新方法。研究了影响该催化褪色反应的因素。方法的线性范围为0.09～7.0 ng/mL,检出限为2.9×10-2 ng/mL。方法用于实际样品的测定。
The catalytic activity of V (Ⅴ) to catalyze the reaction of KClO3 to oxidize methyl red in 0.1 mol / L H3PO4 media was studied by using ascorbic acid as an activator. The catalytic kinetics of trace V (Ⅱ) New method of luminosity. The factors affecting the catalytic fading reaction were studied. The linear range of the method was 0.09 ~ 7.0 ng / mL with the detection limit of 2.9 × 10-2 ng / mL. The method is used to determine the actual sample.
