一、前言为了了解锆在Purex流程中的行为,进行了HDBP萃取~(95)Zr的初步研究。在Purex流程中,所采用的萃取剂是30%TBP-煤油。由于放射性辐照及酸等因素的影响,导致了TBP-煤油的降解。其降解产物有HDBP、H_2MBP、气体产物以及高分子聚合物。此外辐照剂量大时也可产生H_3PO_4、少量丁醇乙醚等异羟肟酸、各种醛、肟羧酸、羟胺、有机硝酸酯、有机硝基化合物、有机亚硝基化合物等。HDBP在工艺流程中与金属
I. Preface In order to understand the behavior of zirconium in Purex process, a preliminary study of ~ (95) Zr HDBP extraction was carried out. In the Purex process, the extractant used is 30% TBP-kerosene. Due to radioactive radiation and acid and other factors, led to the degradation of TBP-kerosene. The degradation products are HDBP, HMBMBP, gas products and polymers. In addition, a large amount of radiation dose can also produce H_3PO_4, a small amount of butanol ether and other hydroxamic acid, various aldehydes, oxime carboxylic acid, hydroxylamine, organic nitrates, organic nitro compounds, organic nitroso compounds. HDBP in the process and metal
