Abstract: 

The surface of activated nanopore sized silica samples was chemically modified by covalent grafting of amine groups, by reaction with N-(2-aminoethyl)-3-aminopropyl-trimethoxy silane. Nanopore sized dipyridyl-functionalized silica gels have been prepared by refluxing grafted amino nanopore sized silica gel with 2,2 -dipyridyl ketone in toluene under the argon atmosphere. The incorporation of nanopore sized organofunctionalized silica gel (DPNSG) particles within carbon paste leads to improved potentiometric detection of copper (II) in acetate medium. The enhanced sensitivity was attributed to selective interaction of copper (II) by the approved surface dipyridyl groups of silica gel. The modified electrode presented high performance, high sensitivity in wide cation activity ranges and good long term stability. The method was satisfactory and was used to determine the copper ion concentration in waste waters, contaminated by this metal.
