基于超痕量钒（Ⅴ）对（ＮＨ４）２Ｓ２Ｏ８氧化苯羟乙酸反应强烈催化作用，氧化产物苯甲醛于－０．９４Ｖ（ｖｓ．ＳＣＥ）处产生一灵敏的单扫描示波极谱波，表面活性剂ＯＰ具有增敏作用。据此建立钒的催化示波极谱分析新方法，线性范围２０～８０００／１０（１２）ｇ／ｍＬ，检测限为８×１０（－１２）ｇ／ｍＬ，用于铝合金分析，获得满意结果。
Based on the strong catalysis of ultra trace trace vanadium (Ⅴ) on the (NH4) 2S2O8 oxybenzene acid reaction, the benzaldehyde oxidation product produced a sensitive single-sweep oscillopolarographic wave at -0.94V (vs.SCE) Active agent OP has a sensitizing effect. Based on this, a new method for catalytic oscillopolarographic analysis of vanadium was established, with a linear range of 20 ~ 8000/10 (12) g / mL and a detection limit of 8 × 10 (-12) g / mL for aluminum alloy analysis result.
