粉晶Ｘ射线衍射、红外光谱、热分析和ＢＥＴ比表面积测定等实验结果表明，铝交联累托石的层间Ｃａ２＋被聚合铝交联柱所取代，层孔高度提高到０．６２ｎｍ，比表面积增大，对水溶液中磷酸根具有明显的选择吸附性，磷去除率可提高３倍以上，文中还讨论了交联累托石对磷酸根的选择吸附机理。
The experimental results of X-ray powder diffraction, FTIR, thermal analysis and BET specific surface area show that the interlayer Ca2 + of the aluminum-crosslinked rectorite is replaced by the polymerized aluminum cross-linked column, and the height of the stratum is increased to 0.62nm, The surface area increases, and the selective adsorption of phosphate in aqueous solution is obvious, and the removal rate of phosphorus can be increased by more than three times. The selective adsorption mechanism of the phosphate on the crosslinked rectorite is also discussed.
