Abstract

Abstract : Why would heavy metal ever go away? Cyclen‐functionalized ethenylene‐based periodic mesoporous organosilica nanoparticles were prepared for heavy metal removal from model solutions. The kinetics and isotherms of adsorption of nickel and cobalt were determined, and these nanomaterials showed high uptake of metals (up to 3.9 mmol g −1 ). They demonstrated pronounced selectivity in the separation of rare earth elements (e.g., neodymium and samarium) from late transition metals, e.g. Ni(II) and Co(II), by adsorption and even more so by controlled desorption.
