AbstractThree types of the extraction chromatographic materials, composed from Aliquat® 336 deposited in the polyacrylonitrile
(PAN) beads and prepared by different procedures, were compared for extraction of rhenium. The best properties were exhibited
when the solid extractant was prepared by impregnation of the ready-made PAN beads. Solid extractant prepared by direct coagulation
of the beads from the suspension of Aliquat® 336 in solution of PAN in nitric acid differs only by lower capacity in dynamic
conditions. Material prepared from the PAN solution in dimethylsulfoxide was the worst because Aliquat® 336 was washed out
from the beads during coagulation of the polymer and the extraction capacity was low. As it is shown, the first two solid
extractants are fully comparable with the commercial TEVA Resin.
