Preparation of Zn 2+ ion-imprinted polymer (Zn-IIP) nanoparticles is presented in this report. The Zn-IIP nanoparticles are prepared by dissolving stoichiometric amounts of zinc nitrate and selected chelating ligand, 3,5,7,20,40-pentahydroxyflavone, in 15mL ethanol-acetonitrile (2:1; v/v) mixture as a porogen solvent in the presence of ethylene glycol-dimethacrylate (EGDMA) as cross-linking,...
This work reports a voltammetric sensor for selective recognition and sensitive determination of mercury ions using glassy carbon (GC) electrode modified with a novel ion imprinted polymeric nanobeads (IIP) and multi-wall carbon nanotubes (MWCNTs). The ion imprinted polymers were prepared by dissolving the certain amount of mercury chloride and 5,10,15,20-tetrakis(3-hydroxyphenyl) porphyrin, in the...
