The fluorinated carbonate BK-1 solvent was studied as a diluent in extraction systems with different extracting agents – CMPO, THDGA, CyMe₄-BTBP, and CyMe₄-BTPhen, which are the most promising molecules for separation of minor actinides and lanthanides. Dependence of the extraction properties of the system on the concentrations of HNO₃ or extracting compound, kinetics of trivalent metal extraction and extraction of the ions by neat diluent (without the addition of extracting agent) were investigated. Based on the obtained results, BK-1 is a promising candidate diluent for f-block metal separation.

氟化碳酸盐作为新的稀释剂，用于f族元素的萃取和分离

氟化碳酸盐BK-1溶剂在具有不同萃取剂CMPO，THDGA，CyMe ₄ -BTBP和CyMe ₄ -BTPhen的萃取系统中作为稀释剂进行了研究，这是分离次minor系元素和镧系元素最有希望的分子。研究了系统萃取性质对HNO ₃或萃取化合物浓度，三价金属萃取动力学和纯稀释剂（不添加萃取剂）萃取离子的动力学的影响。基于所获得的结果，BK-1是用于f-嵌段金属分离的有希望的候选稀释剂。
