Facile preparation of nanocomposite hydrogel sensor for detecting Cu2+ ions contaminant in aqueous media

Novel polymer hydrogel sensor materials were obtained and tested for pH and temperature responsive activity as well as sensitivity to ultralow copper ions content. Copper ion sensitive hybrid composites were prepared via photo-induced copolymerization of a mixture of acrylics and pre-synthesized met...

Description
Summary:Novel polymer hydrogel sensor materials were obtained and tested for pH and temperature responsive activity as well as sensitivity to ultralow copper ions content. Copper ion sensitive hybrid composites were prepared via photo-induced copolymerization of a mixture of acrylics and pre-synthesized methacrylate functionalized ZnO nanoparticles. Sensor activity of the composites is caused by extinguishing fluorescence of nano ZnO under impact of Cu 2+ ions contaminant. It was observed a substantial increasing fluorescence intensity while Cu 2+ ions content falls down from 10 −1 to 10 −6  mol/L. The acrylic matrix demonstrates pH and temperature responsive behavior as well.
