Removal of barium from radioactive aqueous solution by PVA-alginate encapsulated titanium oxide using sunlight and other light types

Barium removal with titania PVA-alginate beads was conducted with sunlight, xenon, black light bulb (BLB) and light emitting diode (LED) lamps. The removal was studied as a function of pH, contact time, temperature and initial concentration. The findings show the removal rate of barium achieved a 98...
