研究了四(4-羟基苯基)BTPhen的萃取性能。在所推荐的Sanex稀释剂环己酮和正辛醇中的液-液萃取研究表明，榄系元素-稀土元素的分离效果优于环己酮；而在正辛醇中分离效率更高。将配体固定在二氧化硅载体上会导致分离因子依赖于水相中硝酸根离子的浓度。该固定化配体还用于萃取过渡金属，在碱和碱土金属存在的情况下，对所考察的所有过渡金属的吸收率为70%。
The extraction properties of tetra(4-hydroxyphenyl)BTPhen have been investigated. Liquid-liquid extraction studies in proposed SANEX diluents, cyclohexanone and 1-octanol, indicate that actinide-lanthanide separation is superior in cyclohexanone; whereas actinide-actinide separation is more efficient in 1-octanol. Immobilization of the ligand onto a silica support results in the separation factor becoming dependent upon the concentration of nitrate anions in the aqueous phase. The immobilized ligand was also applied to the extraction of transition metals, resulting in >70% uptake of all transition metals examined, in the presence of alkali and alkaline earth metals.
