Abstract: The adsorption behavior of crystal violet in Pickering emulsions based on xanthan gum/lysozyme (XG/Ly NPs) nanoparticle stabilizer was studied. The adsorption model was further set up. The results showed that the lower aqueous phase transparency of Pickering emulsions was different with different energy input. The transparency of vortex Pickering emulsion declined as the pH decreased, which was similar with that of XG/Ly NPs solution. While the transparency of homogenized Pickering emulsions was high, which indicating that the interfacial assembly behavior of XG/Ly NPs changed. The adsorption quantity of vortex Pickering emulsion enhanced with the increasing of concentration of crystal violet. During the concentration between 2.5 mg/L and 20 mg/L, its saturated adsorption amount and adsorption rate could reach 10 mg/L and 90%, respectively. The adsorption quantity of homogenized Pickering emulsions was high than that of vortex Pickering emulsion. The adsorption ratecould reach up to 105%.
