研究了温度对９０－１９／Ｕ模拟高放玻璃固化体浸出的影响，得到了不同体系的反应表观活化能，确定了浸泡过程的控速反应步骤。实验发现，用去离子水浸泡，温度的升高会使玻璃固化体浸出反应的控速步骤由离子交换反应向网络溶解反应转变，而在模拟地下水中浸出的控速步骤是离子交换反应，且不随温度而改变。
The effect of temperature on the leaching of 90-19 / U simulated high-content glass solidified body was studied. The apparent activation energy of different systems was obtained, and the step of rate-controlling reaction was determined. It was found that the rate-controlling step of glass solidified body leaching reaction was changed from ion exchange reaction to network dissolution reaction when the temperature was soaked in deionized water, and the rate-controlling step of leaching in simulated groundwater was ion exchange reaction Not change with temperature.
