Synthesis and extraction studies of some new anionic dye extractors
MetadataShow full item record
A new series of dodecyl derivatives of non-cyclic and cyclic ethers, as the extractors have been synthesized by imination, reduction of imines and cyclization steps, and the structures were identified by FT-IR, (1)H-NMR, (13)C-NMR and mass spectroscopy. The extractions abilities of these ligands with some anionic dyes [4-(2-pyridylazo)-resorcinol monosodium salt monohydrate (NaPAR), and sodium picrate (NaPIC), and potassium picrate (KPIC)] were determined by UV-VIS spectrophotometry using liquid-liquid extraction method. In this study, all of the synthesized ligands were generally showed higher extraction ability for Na-dyes.
