It is important to develop chemically selective scavengers for ions such as Ba2+, Ni2+, and Co2+ from complex wastewater for environmental remediation and human health. The current natural and synthetic absorbent materials, however, share the problems of low capacity and poor selectivity. In particular, the selective removal and separation of radionuclides from industrial nuclear wastes with high salt concentrations is a challenge.
