Competitive Bulk Liquid Membrane Transport and Extraction of Cu(II), Ni(II), Zn(II) and Mn(II) Cations Using 5-Methyle-4[thiophen-2-yl-methylen-amino]-3-thio-oxo-1, 2, 4-triazol-5-one and Phthalic Dicarboxaldehyde
The competitive metal ion extraction and transport of Cu(II), Ni(II), Zn(II) and Mn(II) with a S-N donor, i.e. 5-methyle-4[thiophen-2-yl-methylen-amino]-3-thio-oxo-1,2,4-triazol-5-one(ATTT) and oxygen donor, phthalic dicarboxaldehyde(PHDC) compounds was examined and compared each other. Although the...

| Summary: | The competitive metal ion extraction and transport of Cu(II), Ni(II), Zn(II) and Mn(II) with a S-N donor, i.e. 5-methyle-4[thiophen-2-yl-methylen-amino]-3-thio-oxo-1,2,4-triazol-5-one(ATTT) and oxygen donor, phthalic dicarboxaldehyde(PHDC) compounds was examined and compared each other. Although the extraction and transport behavior of Cu(II) and Zn(II) with both ATTT and PHDC ligands is fundamentally similar, but the transport efficiency for Cu(II) is much better than Zn(II) ion. The transport and extraction results closely parallel for the cations using the present ligands. The experiments were buffered (acetic acid/sodiumacetate and formic acid/sodiumformate) at pH 3-7. The concentrations in the all transport and extraction experiments for the cations and ligands were 0.01 M and 1.0 x10-3 M respectively |
