Recovery of Thorium by High-Capacity Biopolymeric Sorbent
The potential of prepared alginate biopolymers as a natural, economic, effective, non-toxic biosorbent was investigated for the recovery of thorium ions in this study. The experiments were carried out to study the effects of various physico-chemical parameters on biosorption and desorption of thorium.

On the identification of Ti-Ta-Nb-oxides in “wiikites” from Karelia [PDF]
Purpose. With respect to the nature of Ti-Ta-Nb-oxides, which are included in the mineral associations that have historically gone by the now outdated name of “wiikites”, there is no unanimity of opinion.

Sorption of Uranium(VI) and Thorium(IV) by Jordanian Bentonite
Purification of raw bentonite was done to remove quartz. This includes mixing the raw bentonite with water and then centrifuge it at 750 rpm; this process is repeated until white purified bentonite is obtained.
