| 摘 要： | 研 究了土壤中有机 矿质复合胶体的金 属离子平衡，结 果显示：在含 Ｃａ２ ＋ ， Ｆｅ３ ＋ ， Ａｌ３ ＋ 的溶 液中，高岭石胡敏酸复合体较蒙脱石胡敏酸复合体吸附较多的 Ｆｅ３＋ ，而吸附的 Ｃａ２ ＋ 和 Ａｌ３ ＋ 则较少；蒙脱石胡敏酸复合体在含 Ｆｅ３ ＋ ， Ａｌ３ ＋ 的溶 液中，释出的 Ｃａ２＋ 较多⒚这些离 子平衡与溶液 ｐ Ｈ 条件有 关，在高岭类复合体中，ｐ Ｈ 的影响更为明显⒚

| Abstract: | The cation equilibrium of organo mineral complex in solution was studied. Results showed that kaolinite humic acid complex adsorbed more Fe 3 and less Al 3 ,Ca 2 in solution than montmorillonite humic acid complex, and montmorillonite type complex released more Ca 2 by Fe 3 and Al 3 in solution. The cation equilibrium between organo mineral complex and solution was affected by pH level, especially for kaolinite humic acid complex. |
