| Abstract: | Al-Ferron timed complex colorimetric method was applied to study on aluminum species and its distribution in catalyst binders aluminum sol. The effects of Al concentration, placing time after dilution and temperature on the aluminum species were investigated. The experimental results showed that Al concentration, placing time after dilution and temperature had the effects on aluminum species of series A, and little effects on the samples of series B. The method had better reliability and repeatability under the condition of sample testing temperature 45 %, Al concentration 0. 000 4 mol . L-1 and placing time after dilution 〈 5 min. Al-Ferron timed complex colorimetric method could be applied to the quality inspection of aluminum sol. |
