2. Aqueous two-phase system - Wikipedia

   en.wikipedia.org/wiki/Aqueous_two-phase_system

   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.

3. Countercurrent distribution - Wikipedia

   en.wikipedia.org/wiki/Countercurrent_distribution

   The simplest form of liquid-liquid extraction is the partitioning of a mixture of compounds between two immiscible liquid phases in a separatory funnel. [2] This occurs in five steps: 1) preparation of the separatory funnel with the two phase solvent system, 2) introduction of the compound mixture into the separatory funnel, 3) vigorous shaking ...

4. Multiphase flow meter - Wikipedia

   en.wikipedia.org/wiki/Multiphase_flow_meter

   Measurement and interpretation of 2 and 3 phase multiphase flow can also be achieved by using alternative flow measurement technologies such as SONAR.SONAR meters apply the principles of underwater acoustics to measure flow regimes and; can be clamped on to wellheads and flow lines to measure the bulk (mean) fluid velocity of the total mixture which is then post-processed and analyzed along ...

5. Extraction (chemistry) - Wikipedia

   Typically, this will be to extract organic compounds out of an aqueous phase and into an organic phase, but may also include extracting water-soluble impurities from an organic phase into an aqueous phase. [1] [2] Common extractants may be arranged in increasing order of polarity according to the Hildebrand solubility parameter:

6. Thin layer extraction - Wikipedia

   en.wikipedia.org/wiki/Thin_Layer_Extraction

   With a typical liquid mass diffusivity in the order of 10 −9 m 2 /s, [2] the characteristic time for diffusion through a 20 micron thick liquid layer is 0.4 s. Therefore, the thinness of both phases (organic and aqueous) causes a relatively "immediate" mass transfer of guest species from one phase to the other, which means that this process has a low mass transfer resistance.

7. Advanced oxidation process - Wikipedia

   H 2 O 2 → HO· + HOO· + H 2 O (Self scavenging and decomposition of H 2 O 2) the reaction steps presented here are just a part of the reaction sequence, see reference for more details. Photocatalytic oxidation with TiO 2: [15] TiO 2 + UV → e − + h + (irradiation of the photocatalytic surface leads to an excited electron (e −) and ...

8. Two-phase flow - Wikipedia

   en.wikipedia.org/wiki/Two-phase_flow

   Different modes of two-phase flows. In fluid mechanics, two-phase flow is a flow of gas and liquid — a particular example of multiphase flow.Two-phase flow can occur in various forms, such as flows transitioning from pure liquid to vapor as a result of external heating, separated flows, and dispersed two-phase flows where one phase is present in the form of particles, droplets, or bubbles in ...

9. Electroextraction - Wikipedia

   en.wikipedia.org/wiki/Electroextraction

   A three phase system extracts anions and cations into the two outer phases while leaving uncharged particles in the middle phase. [6] Convective mixing is restricted to each phase and does not travel between phases. A diagram is given in figure 1. Organic phases that are used typically have small amounts of water added in order to be conductive.
