Composite sorbent for attrition minimization

Attrition is erosion by friction, i.e., wearing down of particles by friction due to water. Powdery materials such as titanium dioxide (TiO2), a well known sorbent, suffers from attrition loss during metal ion recovery, mainly during regeneration of TiO2 for reuse. To minimize the inorganic sorbent...

description Attrition is erosion by friction, i.e., wearing down of particles by friction due to water. Powdery materials such as titanium dioxide (TiO2), a well known sorbent, suffers from attrition loss during metal ion recovery, mainly during regeneration of TiO2 for reuse. To minimize the inorganic sorbent (TiO2) loss, inorganic–organic composite (hybrid) sorbent was prepared from a radical initiated solution polymerization of acrylamide and freshly prepared titanium dioxide. Uranium uptake has been compared with titanium dioxide (freshly prepared), TiO2–polymer composite and virgin polymer. The potential of this composite sorbents for the uranium recovery was ascertained.
