| Abstract: | The classical Ferron timed complex colorimet ric method is improved.With which the content of Al and Fe in inorganic polymer flocculant can be measured synchronously,there by the three species distribution of is knowable.The species distribution of in PSPAFC prepared by different ratio of nAl/nFe,nSiO2/n and nP/n are analyzed by the method.The results showed that the ratio has effect on three species distribution.Content of (b)% is highest,that is about 70%,under the condition of nSiO2/n=2 ∶1,nAl/nFe=7 ∶3,nP/n=3 ∶20.Flocculation characteristics of PSPAFC has been studied by simulated wastewater,that is consistent with the results of species distribution test. |
