Waheed, K. published the artcileDiglycolamide Based Mono and Di-Ionic Liquids Having Imidazolium Cation for Effective Extraction and Separation of Pb(II) and Co(II), Recommanded Product: 2,2′-Oxydiacetic acid, the main research area is lead cobalt diglycolamide ionic liquid imidazolium cation extraction separation.
Two glycolamide based functionalized ionic liquids (ILs) having imidazolium cations namely LI (mono-ionic) and LII (di-ionic) were synthesized for the extraction of Pb(II) and Co(II) from waste water. The synthesized ligands were characterized by FTIR and NMR spectroscopy. The extraction efficiency of both mono- and di-ionic liquids was evaluated in terms of contact time, pH of the aqueous phase and metal ion concentration The metal extraction was carried out at various pH values viz. 2, 4, 6, 8, and 10 whereas, at contact time of 15, 30, 45, 60, and 75 min. The optimized pH of 4 and equilibration time of 75 min was further utilized for extraction at various metal ions concentration (50, 100, 150, 200, and 250 ppm). LI exhibited low equilibration time as compared to LII whereas, both ligands showed maximum extraction at a pH of 4. A very high extraction efficiency of up to 99% for both metals was observed with LI and LII under optimized conditions. In addition to that effective separation of Co(II) and Pb(II) was observed at pH 10.
Russian Journal of Inorganic Chemistry published new progress about Extraction. 110-99-6 belongs to class alcohols-buliding-blocks, name is 2,2′-Oxydiacetic acid, and the molecular formula is C4H6O5, Recommanded Product: 2,2′-Oxydiacetic acid.
