“…Improved interfacial activity is another accomplishment . For example, using ferromagnetic particles as the stabilizer and magnetic response component, Yang et al developed a kind of Pickering emulsions which possessed improved stability, strong interfacial activity, and superparamagnetism . By applying them to separation of chlorobenzene, phenol, and methyl orange from aqueous solution, researchers demonstrated their practical values in rapid organic pollutant disposal in contaminated water.…”

Molecularly imprinted polymers prepared by Pickering emulsion method with lignin as stable particle were used as dispersants in matrix solid-phase dispersion, followed by ultra high performance liquid chromatography with tandem mass spectrometry to research the degradation behavior of matrine in soil. The molecularly imprinted polymers have regular morphology and uniform particles. Moreover, the adsorption experiments and the conditions of matrix solid-phase dispersion were discussed. With the optimal conditions of matrix solid-phase dispersion, the recoveries of matrine were 95.4-98.2%, relative standard deviations were 0.6-5.1%, and the detection limit was 5 ng/g. Moreover, the degradation behavior of matrine in soil was researched, it indicated the half-life of matrine was 2.7-3.2 days, and it was an environmentally friendly botanical pesticide. The method was successfully applied to separate and analyze matrine in soil samples can decrease analysis time, save organic solvents, and improve the selectivity.

“…This leads to the formation of a dense film thus creating a barrier around the droplets giving them a high resistance to coalescence. The particle adsorption or desorption energy: ΔE = γo/w πr 2 (1 ± cos θ) 2 (1) (r is particle radius, γ o/w is the oil-water interfacial tension and θ is the contact angle) is mainly related to their ability to be partially wetted by the two phases of the emulsion [4][5][6]. This wetting of the particles is characterized by an angle of contact between the aqueous phase, the oil phase and the solid particles, measured on the side of the aqueous phase.…”

Pickering emulsions are systems without surfactants, stabilized by solid particles. These emulsions are experiencing a renewed interest, on the one hand, because it is preferable to limit the use of synthetic surfactants for toxicological and environmental reasons and, on the other hand, the need to make new formulations in order to control the drug release patterns by encapsulation or controlled release. Thus, we were interested in the formulation and evaluation of W / O Pickering emulsions stabilized by particles of magnesium oxide with tramadol hydrochloride in the internal phase. The Bancroft rule served as a model for the formulation. The emulsification was carried out by progressively adding an aqueous phase dispersed in an oil-dispersing phase using a turbo rotor stator mixer. The stability of these emulsions was studied using several parameters (droplet size, pH, viscosity, conductivity...) and the qualitative and quantitative analysis of the active ingredient by UV-visible spectrophotometry. The results obtained showed that the dye test and the conductivity measurement confirmed the W / O nature of these emulsions. Some parameters such as droplet size, pH and viscosity were strongly influenced by the amounts of Magnesium oxide particles and the active ingredient. The qualitative and quantitative analysis of the active ingredient confirmed the presence of tramadol in the internal aqueous phase. Thus, we have succeeded in developing a stable W / O Pickering emulsion with magnesium oxide particles. In addition, we were able to encapsulate tramadol in the dispersed aqueous phase.
