文摘
- •
Nanosized TiO2 powder photocatalyst was implanted in the titania polyvinylalcohol-alginate beads.
- •
Removal efficiency of Cd(II) by the beads was verified for different initial concentrations.
- •
Verification of desorption capacity can be reused the beads for five cyclings.
- •
Adsorption kinetics were analysed using the mass transfer factor models.
- •
The resistance of mass transfer could be mainly dependent on external mass transfer.
