Setting the Foundations of Aqueous Three‐Phase Systems (A3PS) in the Quest for a Rational Design

Abstract

This work presents the first in‐depth study of Aqueous Three‐Phase Systems (A3PS) with the main purpose of unveiling their behaviour, hence contributing to the development of this new field. Thus, a complete definition of a quaternary system was carried through by describing all the regions in detail to represent them later on in a regular‐tetrahedral diagram. The three aqueous faces of the tetrahedron demonstrated an undeviating influence in the segregation capacity. Furthermore, a method for comparing Aqueous Biphasis Systems (ABS) immiscibilities was set up in order to allow the evaluation and detection of the “limiting ABS” for the three‐phase region. Finally, all this information was compiled and utilised to obtain a new strategy for an A3PS rational design, which can be applied with ABS libraries or in an experimental approach. In this sense, this strategy represents an undoubted advance towards future studies and development of A3PS, as this sequential application of the constructed knowledge is assumed to save time and resources.

Ionic Liquids Functionalized MOFs for Adsorption

“…Thus, it is critical to effectively separate and remove synthetic colors from the effluent streams. To solve this problem, effective water-filtration techniques should be developed. , In this respect, several types of adsorbent materials, including activated carbon, coal, clay, fly ash, and MOFs, have been researched and reported for effective dye removal from aqueous solutions. , …”
