A flame atomic absorption spectrometric procedure for determining the iron, zinc, manganese, calcium and magnesium contents of slurries prepared from vegetables is described. Samples were first submitted to a mild calcination step and then suspensions were prepared and introduced into an air-acetyle
1,10 Phenanthroline (phen) has been tested as a complexing agent, which is more stable and selective than sodium-diethyldithiocarbamate (DDTC) and ammonium-pyrrolidinedithiocarbamate (APDC), for on-line preconcentration of copper on RP-C 18 material in a microcolumn with a flow injection-flame atomi
