Environment-friendly straw cellulose hydrogel beads (SCHBs) were applied for Cd(II) recovery andrecycling from solution. The SCHBs presented good adsorption capacity for Cd(II) of 95.62 mg/g at 313.5 K. These Cd(II) loaded SCHBs were recycled for CdS in-situ synthesis and employed as photocatalyst in thedegradation of methylene blue under visible light irradiation. Both TEM and SEM images confirmed thatthe recycled CdS nanoparticles within SCHBs are smaller than 20 nm in size, and XRD patterns wereconsistent with the metallic crystallinity of CdS. The recycled SCHBs-CdS composites exhibited excellentphotocatalytic degradation ability and reusability.
