一种吸收光谱电化学电池的研制及其应用

The Design and Application of a Spectroelectrochemistry Cell

本文介绍了一种吸收光谱电化学电池。采用该电池测定了亚铁氰化钾的扩散系数,其值与文献报道吻合。对有机物邻一联甲苯胺进行了定量测定,工作曲线在2×10^(-6)～1.0×10^(-5)mol/L范围内呈良好的线性关系,K-C及A_(max)-C曲线的相关系数分别为0.9988和0.9996。对1.0×10^(-5)mol/L的邻-联甲苯胺溶液,K值的变动系数为1.17％,A_(max)值的变动系数为1.00％。

One kind of absorption spectroelectro chemistry cell has been reported. Using this cell for measuring the diffusion coefficient of K_4Fe(CN)_6we have got the value identical with that reported in the reference. The linearity of the working curves is fine for 2×10^(-6)～ 1.0×10^(-5)mol/ LO-Tolidine solutions. the correlation coefficients ofK-Cand A_(max)—Cplots arc 0.9988 and 0.9996, reapectivcly, For 1.0×10^(-5)mol / L
