通过粉状白钨酸和黄钨酸的离子交换性能的测定,比较了它们之间化学活性的相对大小。用动态法(交换柱法)测得了它们的离子交换容量,计算了与钨原子相联的羟基数目。并用静态法(振荡平衡法)测定了白钨酸对不同阳离子的交换情况及各种鸽酸的pH滴定曲线。
The relative sizes of chemical activity between them were compared by the determination of the ion exchange properties of the powdery tungstic acid and the tungstic acid. Their ion exchange capacity was measured by the dynamic method (exchange column method) and the number of hydroxyl groups associated with the tungsten atom was calculated. And the static method (oscillatory equilibrium method) was used to determine the exchange of different cations of tungstophosphoric acid and the pH titration curves of various pigeon acids.
