“…The isotherm shows the greatest adsorption capacity at 0.245 mmol/g (94.19 mg/g). The results between 0.08 and 0.25 mM show a fast formation of admicelle [30] and the formation of hemimicelles -admicelle [29].…”

“…Although various studies have been reported, there are still different opinions about the surfactant adsorption mechanisms (Laha et al 2009). Adsorption of ionic surfactants is generally correlated with electrostatic forces (Paria and Khilar 2004), whereas hydrogen bonding is considered the main force operating in nonionic surfactants adsorption. After the soil washing, a crucial point becomes the disposal and/or treatment of the corresponding wastes before their discharge or reuse (Chu et al 1998).…”

Background and Purpose Surfactant-assisted soil washing and photocatalysis are well known remediation processes of environmental concern. The application of photocatalysis to treat soil washing extracts containing 4-methylphenol, 4-ethylphenol and 4-tert-butylphenol in the presence of nonionic (C 12 E 8 and C 12 E 23 ) and anionic (SDS) surfactants and some of their binary mixtures was investigated in this work by studying the pollutants degradation in the presence of TiO 2 dispersions irradiated with simulated solar light. Materials and methods Clean soil samples were spiked with the investigated alkylphenols. Aqueous solutions of the chosen surfactants were placed in contact for some hours with the spiked soil samples in a rotatory mixer. The pollutants recoveries were evaluated via HPLC analysis. Photocatalytic experiments were performed in solarbox on aqueous solutions and on aqueous surfactant solutions containing the pollutants. Results The pollutants removal from the soil was proven effective using the examined surfactant solutions. The photocatalytic treatment of the wastes was faster using Brij 35, but also SDS and C 12 E 8 -SDS mixtures can be applied. After 2-5 hours the complete pollutants abatement was obtained, depending on the surfactant chosen and on the amount of TiO 2 employed. On the contrary, the treatment of wastes containing C 12 E 8 was an extremely slow process. Conclusions The photocatalytic approach can be applied to remove the examined aromatic pollutants from the washing wastes, confirming the viable coupling between this advanced oxidation method and the surfactant-based soil remediation treatments. Surfactant adsorption onto TiO 2 and micelles concentration play a dominant role.

“…This consequence in the formation of an electrical double layer to prevent aggregation. 22 Accordingly, Ru 0 NPs acquires positive charges in aqueous solution at basic pHs and therefore, anionic SDS surfactant can easily be absorbed on the surface of the nanoparticle precipitates and form a molecular layer on the surface of the particles to stop their aggregation. Further, the concentration effect of SDS was performed at 5 different molar ratios of [Ru]:[SDS] from 1:25 to 1:200, so as to get better dispersion and lower particle sizes.…”

Here we report a facile synthesis of ruthenium (Ru) Nanoparticles (NPs) by chemical co-precipitation method. The calcination of ruthenium hydroxide samples at 500 o C under hydrogen atmosphere lead to the formation of Ru 0 NPs. The size and aggregation of Ru NPs depends on the pH of the medium, and type of surfactant and its concentration. The X-ray diffraction (XRD), scanning electron microscope (SEM) and transmission electron microscope image (TEM) analyses of particles indicated the formation of Ru 0 NPs, and have 10 to 20 nm sizes. As-synthesized Ru 0 NPs are characterized and investigated their catalytic ability in click chemistry (azidealkyne cycloaddition reactions), showing good results in terms of reactivity. Interestingly, small structural differences in triazines influence the catalytic activity of Ru 0 nanocatalysts. Click chemistry has recently emerged to become one of the most powerful tools in drug discovery, chemical biology, proteomics, medical sciences and nanotechnology/nanomedicine. In addition, preliminary tests of recycling showed good results with neither loss of activity or significant precipitation.
