海带浸泡液中碘的电化学提取

The Electrochemical Extraction of I~ in Solution of Kelp

海带浸泡液中碘的提取一直沿用化学氧化法,该法存在着过氧化及环境污染问题,国内曾在70年代改用电化学氧化法,但当时只限于对实验条件的选择,而在电极材料的研究及应用方面却未见报道。为此,我们试制了一种具有电催化活性的阳极,并对海带浸泡液中I—的电化学氧化进行初步研究。

A graphite electrode which contains some electrocatalytic materials was prepared and used to the research of the oxidation of I- in the solution of kelp. The electrode showed good conductivity and intensity, low overpotential, under the experimental conditions, the oxidizability of I- on the tested electrode increased 10% in comparison with the oxidizability of I- on the pure graphite electrode.
