| 摘 要： | 对聚铁溶液进行ｐＨ值和盐基度的分析和估算，给出了聚铁溶液的极限ｐＨ值和极限盐基度与总溶液铁浓度的关系曲线，最终计算结果表明，在平衡条件下，聚铁溶液的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。随着总溶解铁浓度的不断升高，极限ｐＨ值单调下降，而极限盐基度却单调递增。对于铁含量为１６０ｇ／Ｌ的标准聚铁溶液，其最大ｐＨ值为１．３１４，最高盐基度为１９．９９％。

| Abstract: | The pH values and alkalized degrees were analyzed and estimated for polyferric aqueous solution, then the limit pH values and limit alkalified degrees with different total dissolved ferric concentrations were given. The results indicated that under equilibrium states the pH value and the alkalized degree are closely related; once each of them changes, the other will inevitably take place corresponding changes. With the increase of total dissolved ferric concentrations, the limit pH values uniformly decreased, but the limit alkalified degrees demonstrate the contrary. For the standard polyferric aqueous solution with 160 grams ferric per litter, the maximum pH value was 1.314, and the greatest alkalized degree was 19.99%. |
