“…The adsorption of ODTMA added at concentrations above the CMC (i.e., as micelles) on montmorillonite was complete, even at high initial organic cation concentrations reaching adsorption of 150% of the CEC. Complete adsorption of ODTMA micelles by montmorillonite has been previously shown [39,40].…”

“…Allophane is therefore available for removal of the micelles consisting of anionic surfactants and fats from aqueous phase. In previous studies, some hydrophobic pollutants were removed from water using the layered clay minerals such as montmorillonite and kaolinite hydrophobically modified with the surfactant molecules (Polubesova et al, 2004;Li and Gallus, 2005;Polubesova et al, 2005;Rodoríguez-Cruz et al, 2005;Zadaka et al, 2007;Sánchez-Martín et al, 2008). In addition, the clay minerals adsorbed the micelles formed by adding the surfactant molecules to the polluted water (Polubesova et al, 2004;Polubesova et al, 2005;Zadaka et al, 2007).…”

Micelles, consisting of an anionic surfactant and a fatty acid released from a fat, were removed from an aqueous phase using the ion exchange characteristics of a natural clay mineral, allophane. The UV spectral measurements revealed that the concentrations of the anionic surfactant and the fatty acid in the aqueous phase decreased and that these species were removed from the aqueous phase. The adsorption of the surfactant and the fatty acid onto the allophane was confirmed by FT-IR spectroscopy. Furthermore, this adsorption was confirmed by the adsorption of anthracene added as a probe molecule.

“…Polubesova et al (2005) investigated the removal of anionic pollutants (imazaquin, sulfentrazone, and sulfosulfuron) and neutral pollutants (alachlor, acetochlor, chlorotoluron, and bromacil) from water by micelles of octadecyltrimethylammonium and benzyldimethylhexadecylammonium (BDMHDA) preadsorbed on montmorillonite. Their results indicated that 87-99 % of the pollutants were removed from aqueous phase.…”

Pharmaceuticals (PCs) have been widely detected in natural environment due to agricultural application of reclaimed water, sludge and animal wastes. Their potential risks to various ecosystems and even to human health have caused great concern; however, little was known about their environmental behaviors. Colloids (such as clays, metal oxides, and particulate organics) are kind of substances that are active and widespread in the environment. When PCs meet colloids, their interaction may influence the fate, transport, and toxicity of PCs. This review summarizes the progress of studies on the role of colloids in mediating the environmental behaviors of PCs. Synthesized results showed that colloids can adsorb PCs mainly through ion exchange, complexation and non-electrostatic interactions. During this process the structure of colloids and the stability of PCs may be changed. The adsorbed PCs may have higher risks to induce antibiotic resistance; besides, their transport may also be altered considering they have great chance to move with colloids. Solution conditions (such as pH, ionic strength, and cations) could influence these interactions between PCs and colloids, as they can change the forms of PCs and alter the primary forces between PCs and colloids in the solution. It could be concluded that PCs in natural soils could bind with colloids and then co-transport during the processes of irrigation, leaching, and erosion. Therefore, colloid-PC interactions need to be understood for risk assessment of PCs and the best management practices of various ecosystems (such as agricultural and wetland systems).
