前言萃取剂磷酸三丁酯(TBP)和二(2-乙基己基)磷酸酯(H_2MEHP)的降解产物(如HDBP、H_2MBP和H_2MEHP)的水溶液的辐解情况很少报道。仅在五十年代,有人报道过几种单烷基磷酸酯水溶液的辐解情况,发现除了产生H_3PO_4外,还生成不稳定的酰基磷酸酯;后来,有人报道HDBP、H_2MEHP等在同水相搅拌或溶于水的情况下辐 Introduction The radiolysis of aqueous solutions of extractants TBP and H 2 MEHP (such as HDBP, H 2 MBP and H 2 MEHP) is rarely reported. In the fifties, it was reported that several monoalkyl phosphate aqueous solution of radiation and found that in addition to produce H_3PO_4, but also generate unstable acyl phosphate; later, it was reported that HDBP, H_2MEHP, etc. in the same water with stirring Or in the case of water soluble
