摘要
制备了可溶性聚苯胺掺杂CoCl2修饰玻碳电极,并用循环伏安法测定水中的溶解氧.研究表明:阴极峰电流ipc与水中的溶解氧浓度具有良好的线性关系.将测定结果与碘量法相比较,误差<±3%.另外该法操作简便、快速,所用电极性能稳定,为化学修饰电极用于分析水中溶解氧提供了一种新的途径.
This paper prepares the glassy carbon electrode modified by sofubilised polyaniline mixed with cobalt dichloride and measured the dissolved oxygen in the water with cyclic voltammetny.The research indicates that the cathodic peak current ipC is linear relative with the dissolved oxygen.Compared with iodinetry the deviation of the measurement is below five percent and has remarkable applied value.Moreover,the operation of the method is very simple and quick.The behaviour of electrode is stabe and it offered a new way to apply the modified electrode for measuring the oxygen dissolved in water.
