Tansport and Extraction of metal of Cn(II), Mn(II), Ni(II) and Zn(II) via carriers of Nitrogen and Oxygen groups (Tri-Azol

The Oxygen and Nitrogen donor ligands produced and then were used for membrane transport of Mn(II), Zn(II), Ni(II) and Cu(II) cations. These ligands were used as cation carrier for competitive metal-ion transport and extraction. In the transport experiments, the source and receiving phases were separated by a chloroform phase and in the extraction experiments chloroform was used as an organic phase. In the part of this study, for the ligands, high soluble property in the water was used for extraction and competitive transport and the ligands were solved in the source phase along cations. After complexation of the ligand by some of cations, transport to organic phase was done and then cations were inserted to receiving phase. The major aim of the present research was finding the selectivity of the ligands incomperiments, transport and extraction experiments between Mn(II), Zn(II), Ni(II) and Cu(II) metal cations. For all of the ligands, first of all, extraction was done at diferent buffers, usually 4.5 - 7 and then proper buffer was choosed for experiments by PH curve vs. percent extraction. Transport was done at the suitable buffer for all of the ligands and the transport curves were drawn. In most of the extraction experiments, there was a similar extraction behavior with the results of the competitive metal-ion transport.
