IO hybrid adsorbent to remove hazardous Cadmium(II) from wastewater

In a paper published in NANO, a group of researchers from Hebei University of Technology, Tianjin, China have discovered an effective way to remove heavy metal Cadmium(II) from wastewater. This utilizes the surface-initiated atom-transfer radical polymerization (SI-ATRP) method to graft poly (tert-butyl acrylate) PtBA from the ultrathin pore wall of inverse opal (IO) SiO2.
