研究了线性扫描伏安法中钒(Ⅴ)的吸附溶出催化行为体系,借以分析环境、食品和生物样品。钒浓度与峰电流在10~(-2)～10~(-12)mol/L间按数量级分段成线性关系。最低检出限为6×10~(-13)mol/L,相对标准偏差在8％以下,干扰较少。
The adsorption-desorption catalytic behavior of vanadium (Ⅴ) in linear sweep voltammetry was studied to analyze environmental, food and biological samples. The vanadium concentration was linearly related to the peak current by orders of magnitude between 10 ~ (-2) and 10 ~ (-12) mol / L. The detection limit was 6 × 10 ~ (-13) mol / L, the relative standard deviation was less than 8% and the interference was less.
