Triton X surfactants to form aqueous biphasic systems: Experiment and correlation

On the phase behaviour of polyethoxylated sorbitan (Tween) surfactants in the presence of potassium inorganic salts

“…From the deviation data, it is possible to conclude that equation (2) is able to reproduce satisfactorily the solubility data, in line with previous results reported for other surfactant-based ABS [3].…”

“…On the other hand, our present research line [1][2][3] focused on the characterization and application of surfactant-based ABS for the extraction of biomolecules with industrial interest, also seeks to analyse the effect of different monovalent cations (Na + and K + ) in the phase segregation of several non-ionic surfactants. Therefore, the influence of the cation can be noticed in figure 3, where a comparison with experimental data presented previously [1] for several sodium-based inorganic salts is performed.…”

“…In continuation of our previous research works [1][2][3] involving the characterization of the solubility behaviour of surfactant aqueous solutions in the presence of inorganic and organic salts, liquidliquid equilibrium of aqueous systems containing polyethoxylated sorbitan (Tween) surfactants were investigated at T = 298.15 K.…”

Liquid–Liquid Equilibrium of Aqueous Two-Phase Systems Composed of Nonionic Surfactant (Triton X-100, Triton X-165, or Triton X-305) and Choline Chloride

“…Since they have both hydrophilic and hydrophobic characteristics, the use of surfactants in ATPSs enables modulation of the characteristics of the phases, making these systems more versatile in processes of separation/extraction of strategic analytes. In order to promote the phase segregation, surfactants have been used together with polymers , or organic and inorganic − salts. These systems offer lower interfacial tension, lower costs, absence of toxicity or flammability (in most cases), and short phase segregation times. , Notably, the nonionic surfactants known as Triton X, especially Triton X-100, Triton X-102, and Triton X-114, have been extensively used to obtain ATPSs. ,,− …”

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

“…In the present study, the tetracomponent system conformed by {Potassium phosphate (K 3 PO 4 )+Choline Glycinate (ChGly)+Triton X‐102+H 2 O} at 30 °C was analysed. As reported before, {K 3 PO 4 +Triton X‐102+H 2 O}, {ChGly+Triton X‐102+H 2 O} and {K 3 PO 4 +ChGly+H 2 O} are able to engender ABS and, therefore, according to Mace et al . the four components should be able to generate an A3PS.…”
