【摘要】 为优化Purex流程2A工艺条件,进行了大量串级实验,结果表明,当2AF酸度为4.5mol/L,Pu浓度为1.6g/L,8级萃取,7级洗涤,萃取时间为lmin,2A段在保证Pu收率的前提下,实现将Pu浓度浓缩8倍是可行的。更多还原

【Abstract】 A lot of cascade experiments were carried out to optimize the precessing conditions of 2A in Purex process.The results showed that,when acidity was 4.5mol/L,the concentration of Pu was 1.6g/L,8 stages of extraction and 7 stages of syringe,and the extraction time was 1min,it was possible to condense 8 times of the concentration of Pu,when the recovery of Pu was acceptable in 2A.更多还原
