1引言 在碱性介质中,痕量Co(Ⅱ)见对H2Q2氧化邻联甲苯胺(o-Tolidine)的显色反应具有强烈的催化作用,探讨了利用该反应进行痕量Co(Ⅱ)测定的影响因素,建立了测定痕量Co(Ⅱ)的催化动力学光度法,该方法的灵敏度为1.78 × 10-6g/L,测
1 Introduction In alkaline media, traces of Co (Ⅱ) see the H2O2 oxidation o-Tolidine (o-Tolidine) color reaction has a strong catalytic effect of the use of the reaction trace Co (Ⅱ) determination , The kinetic spectrophotometry was established for the determination of trace Co (Ⅱ). The sensitivity of this method was 1.78 × 10-6g / L,
