Özet
The extraction of Zn(II) and Cu(II) from hydrochloric acid solutions has been investigated using trioctylamine in methyl isobutyl ketone (MIBK), diethyl ether (DEE) and isoamyl acetate (IAA), As a result, it was found that the extraction efficiency for Zn(II) and Cu(II) of MIBK, DEE and IAA is in the order DEE > IAA > MIBK. The batch method was used for the extraction of Zn(H) and Cu(II). The method was applied to the analysis of the elements studied in waste water. In addition, the back extraction of elements was studied. The, influence of foreign ions on the extraction of Zn(II) and Cu(II) was investigated. Blank values were low and recoveries were 99.4% and 77.1% for Zn(II) and Cu(H), respectively, at 95% confidence level. Detection limits (3 sigma) were 2.3 mu g.L-1 for Zn and,0.0.5 mu g.L-1 for Cu(II).
