Barium(II) 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(II) achieved a 98% maximum within 130 min under sunlight. The beads were found to be easily isolated from the aqueous solution and could be reused a minimum of 5 times without losing the original properties. Barium(II) reduction fitted best with the pseudo second-order rate model with a coefficient of determination (R²) of 0.9938.
