| Abstract: | A novel type of gassensitive electrode,a gas thin-layer electrode(GTLE),has been constructed by using hydrophobic gas diffusing electrode technique.Distinctive peaks appeared on linear sweep voltammetry curves as the result of exhaustive electrolysis of reactants within GTLE.The charge(Qp)correlated to the current peak was directly proportional to the amount of the reactant component in the pores of GTLE,thus its concentration in the gas sample can be detected. The measuring system is simple in construction,capable of fast sampling(<5S),with lower temperature coefficient(-0.1-0.3%/℃),high sensitivity and good stability. |
| Keywords: | Gassensitive electrode Hydrophobic gas diffusing electrode Gas thin-layer eletrode Bulk electrolysis |
