模拟高放玻璃固化体浸出行为的研究Ⅰ.温度对固化体浸出的影响
STUDIES ON LEACHING BEHAVIOR OF THE SIMULATED HLW-GLASS FORM 1.EFFECTS OF TEMPERATURE ON LEACHING BEHAVIOR
【摘要】 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。
【Abstract】 The effect of temperature on the simulated HL W-glass form is studied.The activation energies are obtained and the rate-controlling process of glass corrosion is determined.The experimental results show that in deionized water,with temperature increasing,the rate-controlling process of glass corrosion is changed from ion-exchange to network dissolution,In simulated under ground water,the rate-controlling process of glass corrosion is ion-exchange,which is independent on temperature.
