摘要：

The discriminatory power of dialysis, ion exchange and membrane filtration techniques to identify hydroxyaluminosilicate (HAS) formation in solutions of near-physiological aluminium concentration has been tested. Results indicate the hitherto unreported formation of HAS in solutions of low total aluminium concentration. The identification of these species was dependent upon both the pH and the silicic acid concentration of the solution. It was also found that the method of preparation of solutions influenced the discriminatory power of the different techniques and this led us to suggest that the mechanism of HAS formation involved the poisoning of aluminium hydroxide polymerization by silicic acid.
