Abstract. Aqueous biphasic extraction (ABE) processes offer the potential for low-cost, highly selective separations. This countercurrent extraction technique involves selective partitioning of either dissolved solutes or ultrafine particulates between two immiscible aqueous phases.

Browse book content. About the book. Search in this book. Search in this book Nonaqueous biphasic systems provide complementary properties to aqueous biphasic systems for the extraction of neutral organic compounds of low-water solubility and for compounds unstable in water.

Metal ion separations have since come to constitute an. Aqueous biphasic systems (ABS) or aqueous two-phase systems (ATPS) are clean alternatives for traditional organic-water solvent extraction systems. ABS are formed when either two polymers, one polymer and one kosmotropic salt, or two salts (one chaotropic salt and the other a kosmotropic salt) are mixed at appropriate concentrations or at a particular temperature.

AQUEOUS BIPHASIC SYSTEMS (ABSS) FOR BIOSEPARATIONS | Aqueous Two-Phase Systems (ATPS) provide a powerful method for separating (bio)molecules. Robin D. Rogers is the author of Aqueous Biphasic Separations ( avg rating, 0 ratings, 0 reviews, published ), Green Industrial Applications of Io.

Aqueous biphasic systems occur when certain solutes cause an aqueous solution to separate into two aqueous phases. Beijerinck first noted, inthe 'incompatibility' of certain polymers in aqueous solution.

An extreme in aqueous biphasic separations, using just H 2 O, can be shown using mixtures of low-density ultraviscous liquid. Aqueous biphasic systems (ABSs), in which two aqueous phases with different compositions coexist as separate liquids, were first reported more than a century ago with polymer solutions.

Recent observations of ABS forming from concentrated mixtures of inorganic salts and ionic liquids raise the fundamental question of how “different” the components of such mixtures should be for a liquid Cited by: 2.

Much of the theory outlining the effect of biphasic systems on the apparent equilibria was outlined by Karel Martinek and his co-workers at Lomonosov Moscow State University.

Metal ion separation and preconcentration constitute the pivotal step in numerous analytical, purification, and waste treatment processes. Increasing environmental regulations and growing economic incentives imply that separation science will be essential to the future of industrial processing.

Applicability of protic-ionic-liquid-based aqueous biphasic systems. The applicability of the investigated thermoreversible IL-based ABS was further evaluated for separation processes, using two added-value proteins, namely cytochrome c and by: Aqueous Two-Phase Systems: Methods and Protocols (Methods in Biotechnology) this phenomenon is useful in biotechn- ogy for product separations.
