Kinetics of aluminum hydrolysis: measurement and characterization of reaction products. Academic Article uri icon


  • A timed colorimetric analysis procedure is described to characterize products formed during aluminum hydrolysis. The procedure is based on measuring the rate and extent of reaction of the hydrolysis products with ferron and can provide information on the amounts and relative sizes of the hydrolysis products. The procedure was applied to partially neutralized solutions of aluminum sulfate at dilute concentrations (0.1 mM Al). No particles of a size similar to the Al13 polymer were found in these solutions. Marked differences in the characteristics of hydrolysis products formed in batch and continuous flow reactors were observed. Four types of aluminum species were measured in effluents from continuous flow reactors. Two of them were characterized with respect to their dissolution rates in a timed colorimetric analysis procedure. 1986, American Chemical Society. All rights reserved.
