Polyaniline Mixed With CoCl2 Modified Glassy Carbon Eelectrode for Determination of Dissolved Dioxygen in Water |
| |
| Abstract: | 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. |
