| Resumo: | Ammonium pyrrolidine-dithiocarbamate (APDTC) and methyl-isobutyl-ketone (MIBK) extractant were
jound to be considerably improved by the addition of nbutylamine especially for the chemical analysis of Cd(II)
and Zn(II) ions. Solvent extraction oj the bivalent metal ions is a function of pH and the concentration
of APDTC and nbutylamine. Cd(II) and Zn(II) ions exhibit considerable flame spectrometric signal
enhancement for pH ranges from 7 to 12 and 2 to 12 respectively when APDTC-nbutylamine-MIBK was
used as the extractant in place oj APDTC-MIBK. The signal enhancement observed may be interpreted
in terms of the formation of synergistic amine adduct and/or mixed solvent effect. |
