| 摘 要： | 由聚磷氯化铝的２７Ａｌ核磁共振谱图的分析结果表明，磷酸盐的引入对聚合铝的特定形态ＡｌＯ４Ａｌ１２（ＯＨ）２４（Ｈ２Ｏ）７＋１２有显著影响；影响程度取决于Ｐ／Ａｌ值，并随Ｐ／Ａｌ值增大ＡｌＯ４Ａｌ１２（ＯＨ）２４（Ｈ２Ｏ）７＋１２含量减少，由此推测出一种新形态ＰＯ４Ａｌ１２（ＯＨ）２４（Ｈ２Ｏ）９＋１２。

| Abstract: | It has been found, by means of 27 Al NMR spectroscopy, that phosphate has distinct effect on the special species AlO 4Al 12 (OH) 24 (H 2O) 7+ 12 .The content of AlO 4Al 12 (OH) 24 (H 2O) 7+ 12 decreased with the increase of P/Al (molar ratio of phosphate to aluminum) value, with a new species PO 4Al 12 (OH) 24 (H 2O) 9+ 12 derived. |
