| Abstract: | The classical Ferron timed complex colorimetric method is improved by determining pH value,wavelength,solution concentration and reagents,with which the content of Al and Fe in concomitant solution can be measured synchronously,thereby the species distribution of in actual containing Fe/Al multipolymer is knowable.The method veracity and validity is well presented by the comparatively high absorbency of complexe and regression coefficient 0.99 of specification curve under the condition of pH 5.0,λ362 nm,total concentration of within the level range of 1×10-5～1×10-4 mol/L.The species distribution of in PSPAFC prepared by different ratio of nAl/nFe,nSiO2 /n and nP/n are analyzed by the method.Results showed that the ratio has effect on the species distribution of.Content of(b)% is highest value of 50.46% under the condition of nSiO2/n 1:2,nAl/nFe 7:3,nP/n 2:20,and reducing with the increase of nFe/nAl and nSiO2/n. |
