Catalytic determination of copper in blood plasma using flow-injection biamperometry
A method for the determination of copper based on the catalytic effect of Cu(II) on the oxidation of thiosulphate by Fe(II) is described. Fe(II) formed in this reaction in the presence of an excess of Fe(III) allows the use of amperometric detection with two polarized platinum wire elecrodes. At a p...

Fe(II) formed in this reaction in the presence of an excess of Fe(III) allows the use of amperometric detection with two polarized platinum wire elecrodes. At a polarizing voltage voltage of 80 mV a linear dependence of current intensity on Cu(II) concentration is obtained in the range of Cu(II) concentrations present in blood plasma. In determinations with a sampling rate of 70 h^-^1 a satisfactory agreement was obtained between the results of flow-injection analysis with biamperometric detection and flame atomic absorption spectrometry.</subfield></datafield><datafield tag="533" ind1=" " ind2=" "><subfield code="f">Elsevier Journal Backfiles on ScienceDirect 1907 - 2002</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Michalowski, J.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Trojanowicz, M.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">in</subfield><subfield code="t">Analytica Chimica Acta</subfield><subfield code="d">Amsterdam : Elsevier</subfield><subfield code="g">281(1993), 2, Seite 299-304</subfield><subfield code="w">(DE-627)NLEJ173450067</subfield><subfield code="w">(DE-600)1483436-4</subfield><subfield code="x">0003-2670</subfield><subfield code="7">nnns</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:281</subfield><subfield code="g">year:1993</subfield><subfield code="g">number:2</subfield><subfield code="g">pages:299-304</subfield></datafield><datafield tag="856" ind1="4" ind2="0"><subfield code="u">http://linkinghub.elsevier.com/retrieve/pii/0003-2670(93)85185-M</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_USEFLAG_H</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">ZDB-1-SDJ</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_NL_ARTICLE</subfield></datafield><datafield tag="951" ind1=" " ind2=" "><subfield code="a">AR</subfield></datafield><datafield tag="952" ind1=" " ind2=" "><subfield code="d">281</subfield><subfield code="j">1993</subfield><subfield code="e">2</subfield><subfield code="h">299-304</subfield></datafield></record></collection>
