| 摘 要： | 为聚铝溶液进行了ＰＨ值和盐基度的分析和估算，给出了聚铝溶液的极限ＰＨ值和极限盐基度与总溶解铝浓度的关系曲线，最终计算结果表明：在平衡条件下，聚铝溶液的ＰＨ值和盐基度具有相关性，即当基中一个参数发生变化时。另一个参数必然要发生相应的改变。

| Abstract: | The values of pH and the alkalized degree were analyzed and estimated for polyaluminum aqueous solution in this work. The effects of total dissolved aluminum on the limited value of pH and the limited alkalized degree were also discussed. The calculated results indicated that the pH value and the alkalized degree are closely related to those obtained from the equilibrium states. It was also found that once each of them changes, the other will inevitably take place corresponding changes; for the standard polyaluminum aqueous solution with 10 % of Al 2O 3 the maximum of pH values is 4.071, and the greatest alkalized degree is 87 %. |
