Liquid chromatography of palladium and non-ferrous metal chelates with 1-(2-pyridylazo)-2-naphthol.
1-(2-Pyridylazo)-2-naphthol has been used for extraction concentration of palladium, copper, cobalt and nickel from aqueous solutions and subsequent separation of the chelates obtained, by means of high-pressure liquid chromatography. A technique for determining microamounts of palladium in aqueous solutions in the presence of 100-fold ratio of copper and 80-fold ratio of cobalt has been develo...
متن کاملHighly copper(II) ion-selective transport through liquid membrane containing 1-(2-pyridylazo)-2-naphthol.
often an important process in industry and chemical analysis. Liquid-membrane transport in which the extraction and stripping operations are combined in a single process reduces the solvent inventory requirement, and also allows the use of expensive and highly selective extractions, which otherwise would be uneconomic in solvent extractants. For these reasons, liquid-membrane transport has attr...

15 صفحه اولLiquid - Liquid Extraction of 2, 3-Butanediol from Fermentation Broth
Recovery of metabolites from fermentation broth by solvent extraction can be used to optimize fermentation processes. End-product reutilization, low product concentration, large volumes of fermentation broth and the requirements for large bioreactors, in addition to the high cost largely contributed to the decline in fermentative 2, 3-butanediol production. Extraction can ...
