In the solution of H2SO4,trace Ni(Ⅱ) inhibits strongly the decolorization reaction and its inhibition extent was linear with the contents of Ni(Ⅱ)in a certain range.
01mol/LH2SO4溶液中,痕量镍对高碘酸钾氧化胭脂红的褪色反应有较强的阻抑作用,阻抑的程度与加入镍的浓度呈线性关系,由此建立了测定镍的光度分析新方法。
On the basis of such a inhibition,a kinetic spectrophotometry determining trace copper(Ⅱ) is astablished.
基于这种阻抑作用建立了一种测定Cu(Ⅱ )的动力学分光光度法 ,Cu(Ⅱ )在 1 。
