Abstract:The specific conductivity oscillation systems of Pickering emulsions composed of cyclohexane-water-calcium carbonate and cyclohexane-methanol-calcium carbonate were designed and prepared for the first time. Potassium chloride at constant concentration was acted as background electrolyte. The data collection system controlled by a computer was used to measure continuously specific conductivity oscillation of Picketing emulsions. The effects of solid powders, assistant surfactant, and polarity of oil and water, on specific conductivity oscillation were explored. It was found that the average amplitude of specific conductivity for emulsion of cyclohexane-water-calcium carbonate was about 400μS·cm^-1 which was larger than that by single surfactant. However, the average amplitude of specific conductivity for emulsion of cyclohexane-methanol-calcium carbonate was about 10 μS·cm^-1 which was nearly the same as that by single suffactant. When a little TX-100 was added to the emulsion, the amplitude of specific conductivity oscillation became smaller. The specific conductivity oscillation in two types of emulsions could last tbr a few days.
