The theoretical results indicate that the response time is dependent upon membrane properties, membrane geometry, internal electrolyte composition, the dissociation constant of the conjugate reaction, the initial gas concentration in the internal electrolyte, and the gas concentration in the evaluation sample. The theoretical prediction is in good agreement with the experimental result. A method for determining a gas-sensing probe' s dynamic parameter is proposed in this paper also.展开更多
文摘The present paper covers the response dynamics of a gas-sensing membrane probe, which is described by the dynamic differential equation based upon a steady-state diffusion process. The theoretical results indicate that the response time is dependent upon membrane properties, membrane geometry, internal electrolyte composition, the dissociation constant of the conjugate reaction, the initial gas concentration in the internal electrolyte, and the gas concentration in the evaluation sample. The theoretical prediction is in good agreement with the experimental result. A method for determining a gas-sensing probe' s dynamic parameter is proposed in this paper also.
