| Abstract: | By a coulostatic perturbation meter and a computer as on-line measurement system, the cooling water was monitored. Based on the analysis of E-T attenuation curves,relevant parameters, Rp and Rf, in equivalent circuit for the system were obtained. The factor of pH values, which affect the application of polyphosphate inhibitor in the teratment of circulating cooling water, were studied, so the situatiion of film-forming could be reported at all times, corrosion of the systems could be also reflected sensitively. |
