Advances in the area of sample preparation are significant and have been growing significantly recent years. This initial step analysis is essential must be carried out properly, consisting a complicated procedure with multiple stages. Consequently, it corresponds to potential source errors will determine, at end process, either satisfactory result or fail. One advances this field includes miniaturization extraction techniques based on conventional procedures such as liquid-liquid solid-phase extraction. These modern gained prominence face traditional methods since they minimize consumption organic solvents volume. As another feature, possible reuse sorbents, its coupling chromatographic systems might automated. The review emphasize main liquid-phase microextraction, well those upon use sorbents. first group currently popular single drop hollow fiber dispersive microextraction. In second group, microextraction in-tube stir bar sorptive extraction, micro by packed sorbent highlighted. approaches, common, aim determination analytes low concentrations complex matrices. article describes some characteristics, advances, trends miniaturized techniques, their current applications food, environmental, bioanalysis fields.

Review of Microfluidic Liquid–Liquid Extractors

Industrial & Engineering Chemistry Research, Год журнала: 2017, Номер 56(27), С. 7593 - 7622

Опубликована: Июнь 15, 2017

During the last few decades, microfluidic liquid–liquid extractors have been developed to address need for separating solutes in analytical chemistry and efficiently recovering products reactors. This review classifies various into three major groups based on their flow arrangement: stop-flow (MEs), cocurrent MEs, countercurrent MEs. Each group is further classified several subcategories pattern and/or working principle. The focuses how establish these of extractors, including difficulties corresponding solutions establishing as well advantages disadvantages. ends with conclusions outlook field.

Continuous Synthesis of Nanocrystals via Flow Chemistry Technology

Small, Год журнала: 2019, Номер 16(15)

Опубликована: Ноя. 21, 2019

Abstract Modern nanotechnologies bring humanity to a new age, and advanced methods for preparing functional nanocrystals are cornerstones. A considerable variety of nanomaterials has been created over the past decades, but few were prepared on macro scale, even fewer making it stage industrial production. The gap between academic research engineering production is expected be filled by flow chemistry technology, which relies microreactors. Microreaction devices technologies synthesizing different kinds discussed from an point view. advantages microreactors, important features systems, apply them in syntheses salt, oxide, metal, alloy, quantum dot summarized. To further exhibit scaling‐up nanocrystal synthesis, recent reports using microreactors with gram per hour larger rates highlighted. Finally, example 10 tons CaCO 3 nanoparticles day introduced, shows great potential processes transfer lab industry.

Lactic Acid Extraction and Mass Transfer Characteristics in Slug Flow Capillary Microreactors

Industrial & Engineering Chemistry Research, Год журнала: 2016, Номер 55(16), С. 4691 - 4702

Опубликована: Апрель 7, 2016

Capillary microreactors operated under the slug flow regime were investigated for separation of lactic acid from aqueous phase using liquid–liquid reactive extraction. The experiments performed at a 1:1 ratio to organic phases in setup consisting an inlet Y-type mixer connected with poly(tetrafluoroethylene) capillary microreactor and subsequently outlet Y-shape splitter. extraction (intake: 0.11 0.055 M water) 15% (v/v) tri-n-octylamine n-octanol ambient conditions approached equilibrium after about 90 s without noticeable emulsion formation. measured performance can be well described by physical mass transfer model according penetration theory (developed experimental study acetanilide water n-octanol) combined instantaneous irreversible reaction assumption.
