Extraction characteristics are given for solid extractants based on polysorb matrices made by introducing the extraction agent (D2EHPA or a mixture of D2EHPA + TBP) into the matrix in the cold. Results for actinoids (curium and californium) are compared with those from liquid extraction. The higher the content of the agent in the solid and the lower the acidity of the aqueous solution, the more similar the results to those from liquid extraction. The solids are inferior to liquid extraction as regards capacity characteristics: the capacity of the agent in the solid is not used to 100%.
