Biomass material - undulating venus shell - supported nanoscale zero-valent iron for the adsorption of Pb2+ and Cd2+ ions in aqueous solution

Shengxu Luo & Zheng Wang
Nanoscale zero-valent iron (NZVI) has a high adsorption capacity for heavy metals, but easily forms aggregates. Herein, preprocessed undulating venus shell (UVS) is used as support material to prevent NZVI from reuniting. The SEM and TEM results show that UVS had a porous layered structure and NZVI particles were evenly distributed on the UVS surface. A large number of adsorption sites on the surface of UVS-NZVI are confirmed by IR and XRD. UVS-NZVI is utilized...
