Popis: | A new sorbent for transition elements was prepared in a one-step synthesis by encapsulation of a pyrazolone ligand in a surfactant-templated silica. This new material was characterized by X-ray diffraction (XRD), nitrogen physisorption and transmission electron microscopy (TEM). The material presents a lamellar symmetry with a pore diameter of 39 A. The use of a cationic surfactant allows a high loading of ligand (0.43 mol kg−1), associated with complete accessibility of the ligand to the aqueous phase. A sorption capacity of 0.2 mol kg−1 was observed for copper ions in a NaNO3 0.01 M medium. Complete elution of copper species is possible with HNO3 1 M. |
