Özet

Applications of the hexamethylene-dithiocarbamic acid hexamethyleneammonium salt (HMDTC-HMA) coprecipitation method for the preconcentration and separation of lead (II), iron(III), cadmium(II), nickel(II), cobalt(II) and copper(II) ions in seawater samples, dialysis concentrates and some textile samples have been performed prior to their atomic absorption spectrometric determinations. The influences of the main components of the samples as matrix on the quantitative separation and preconcentration of analyte ions were investigated. The concentration W the metal ions detected after preconcentration was in agreement with the added amount. The relative standard deviations of the determinations are generally lower than 10%.
