Abstract

An integrated HPF-system using HPLC and HT-HHP-nebulizer is used for matrix separation by the determination of heavy metals in highly concentrated solutions with FAAS. The separation of the matrix (NaCl) is achieved in a HPLC RP-C18 column after heavy metal complexing with trans-1,2-diaminciclohexane-N,N,N',N'-tetraacetic acid (CDTA). Matrix separation and the metal determination can be realized in less than one minute, without any interference from the matrix. The detection limits of Cd(II), Co(II), Cr(VI), Cu(II), Mn(II) and Zn(II) by FAAS were improved in one order of magnitude in compare with the direct determination by pneumatic nebulization nebulizer.
