title: Properties of the copper(II)-histidine complex obtained after dialysis of human plasma with histidine.
abstract: The copper(II)-histidine complex obtained following dialysis of human plasma with histidine was investigated using various types of extraction systems and ion exchange resins. According to the results obtained, the Cu(II)-histidine complex formed under the dialysis conditions has one positive charge. Preconcentration of copper from the dialysis solution was achieved by its extraction as a dithiocarbamate complex and by sorption on cation-exchange resin or onto chelate sorbent.
