“…Because the surfactant solutions above 1 wt % salt were not aqueous stable at 75 °C, subsequent experiments at the high temperature were done using salt concentration below or at 1 wt %. Note that the salt tolerance of the surfactant could be increased by the addition of EO groups 64 to the surfactants, and this concept would be explored in the future work.…”

Multistimuli-Responsive Foams Using an Anionic Surfactant

et al. 2018

In this work, we report a novel class of a commercially available surfactant which shows a multistimuli-responsive behavior toward foam stability. It comprises three components-a hydrophobe (tristyrylphenol), a temperature-sensitive block (polypropylene oxide, PO), and a pH-sensitive moiety (carboxyl group). The hydrophobicity-hydrophilicity balance of the surfactant can be tuned by changing either the pH or temperature of the system. At or below pH 4, the carboxyl functional group is dominantly protonated, resulting in zero foamability. At higher pH, the surfactant exhibits good foamability and foam stability marked with a fine bubble texture (∼200 μm). Foam destabilization could be achieved rapidly by either lowering the pH or bubbling CO gas. At a fixed pH in the presence of salt, increasing the temperature to 65 °C resulted in rapid defoaming because of the increased hydrophobicity of the PO chain. This stimuli-induced stabilization and destabilization of foam were found to be reversible. We envisage the use of such a multi-responsive foaming system in diverse applications such as foam-enhanced oil recovery and environmental remediation where spatial and temporal control over foam stability is desirable. The low-cost commercial availability of the surfactant further makes it lucrative.

“…The adsorption data of the two resins with respect to each phenolic compound are quantitatively compared in terms of the adsorption percentage using two different concentrations of both resins (5 g L -1 and 50 g L -1 ), which are the smallest and the average concentrations used in the current work. The selectivity coefficient (K) with respect to tyrosol was also determined as the ratio between adsorption percentages between each phenolic compound and tyrosol [31].…”

 The competitive adsorption of a large number of phenolic compounds was assessed from olive mill wastewater.  Higher selectivity coefficient for phenol over hydroxytyrosol was displayed on FPX66. The adsorption and the recovery percentage of hydroxytyrosol on MN202 was greater than 91 %. FPX66 was exhibited a multilayer adsorption characteristic, whereas a monolayer adsorption was attributed to MN202.
