Investigation of the adsorption of a mixture of two anionic surfactants, AOT and SDBS, on silica at ambient temperature

RSM, ANN-GA and ANN-PSO modeling of SDBS removal from greywater in rural areas via Fe2O3-coated volcanic rocks

“…Combined with the energy spectrum, it can be seen that SiO 2 is the pillar structure of volcanic rock, while SDBS has adsorption behavior on SiO 2 . 38 The Si-O-Al stretching vibration was registered at around 785 cm À1 for VR and Fe 2 O 3 -VR and showed that the Si-O-Al framework remained undistorted aer modication. 39 Moreover, a new peak at 642 cm À1 was distributed to the Fe-O group of Fe 2 O 3 aer modication, indicating that Fe 2 O 3 was attached to the VR.…”

Surfactant mixtures: A short review

“…For a different study on a hydrophilic surface, the composition was found to be the same as the micellar composition (McDermott et al, 1993). As has been commonly found for particulate systems and will be discussed in more detail below, a mixture can have higher adsorption than the two individual surfactants (Woods et al, 2011), even in the case where one of the surfactants was non‐adsorbing without the other being present (Wolanin et al, 2021). Some papers have examined morphology changes with mixture composition at these flat surfaces using atomic force microscopy (Saino et al, 2021; von Rybinski et al, 2015).…”

Fabrication of Polystyrene Sulfonate-Chitosan (PSS-Chitosan) Membrane as Dodecyl Benzene Sulfonate (DBS) Adsorbent in Laundry Wastewater

“…However, this method has its drawbacks, including the inability to provide data on pollutant degradation as metal photocatalysts require exposure to UV light and the potential risk of metal bioaccumulation in the bodies of aquatic organisms [17]. Another method being developed is the adsorption of anionic surfactants using silica [18] and graphene [19] as adsorbents. Due to the weak bond between the adsorbent and anionic surfactants and the silica adsorption methods can reduce the selectivity for these substances [20].…”
