[Simultaneous determination of trace Ni2+, Mn2+, Zn2+ and Cu2+ with microwave derivatization/ion-pair high performance liquid chromatography/meso-tetra(4-sulfophenyl)-porphyrin spectroscopy].


The best conditions for the reaction of meso-tetra(4-sulfophenyl)-porphyrin (TPPS4) with Mn2+, Ni2+, Zn2+ and Cu2+ have been investigated. A method for the fast determination of Ni2+, Mn2+, Zn2+ and Cu2+ has been developed: microwave derivatization at 750 W for 3 min, C18 column, acetonitrile-water(22.5:77.5, volume ratio) as mobile phase with… (More)
