The determination of trace elements in mineral water by preconcentration with ammonium pyrrolidinedithiocarbamate (APDC) is described. Samples were spiked with an internal Ga standard and the precipitated dithiocarbamates of trace elements were separated by Ðltration through a Nuclepore Ðlter. A sma
A bidentate chelating agent has been proposed to preconcentrate seven metal ions dissolved in an aqueous sample for their simultaneous determination usiug energy-dispersive x-ray fluorescence spectrometty. The metal ions are precipitated as their polymeric piperaxino-1,4-bis(dithiocarbamate) chelate
