贵金属钯是现代工业的重要材料,资源十分有限,提取高放废液中裂变产物钯,既可避免钯金属对高放废液玻璃固化过程的影响,又可起到缓解钯资源的短缺。三异丁基硫化膦(TiBPS)是一种新型的中性有机膦萃取剂,在硝酸体系中,该萃取剂对贵金属钯具有良好的萃取性能。本工作进行了三异丁基硫化膦的合成方法研究,利用三异丁基膦与单质硫反应制备了TiBPS,通过减压蒸馏
Precious metal palladium is an important material in modern industry and its resources are very limited. Extraction of fission product palladium from high-level liquid waste can not only avoid the influence of palladium metal on the glass curing process of HLW, but also alleviate the shortage of palladium resources. Triisobutyl phosphine sulfide (TiBPS) is a new type of neutral organic phosphine extractant, which has good extraction performance for noble metal palladium in nitric acid system. In this work, the synthesis of triisobutylphosphine sulfide was studied. TiBPS was prepared by the reaction of triisobutylphosphine and elemental sulfur,
