摘要
研究了羟胺浓度、酸度、时间及稳定剂浓度对预处理效果的影响，给出了羟胺预处理改善铀线二循环钌去污的工艺条件。结果表明，单独采用羟胺进行预处理，对钌的去污效果较差，在预处理体系中加入少量肼，可得到满意结果。
The Influences of hydroxylamine concentration , pretreatment time , acidity and the concen tration of stabilizer have been studied ,and the best pretreatment condition for the improvement of Ru decontamination in uranium purification cycle by hydroxylamine pretreatment has been ob tained. The results show that the no satisfactory result can be obtained by solely using hydroxy lamine as pretreatment agent unless a small amount of hydrazine is added into the pretreatment system as stabilizer.
