: micellar-enhanced ultrafiltration; zinc ion; surfactant; micelles ...[1] proposed to use polymer or surfactant modified ultrafiltration. In 1979, LEUNG[2] first removed trace metal ion by using MEUF, and since then the technology has been studied. The method was easy......
was synthesized directly from solution of industrial YCl3 by method of oxalate precipitation through super-micro-reactors made by complex non-ionic surfactant. The purity and diameter of Y2O3 particles were controlled by such processing parameters as concentration of YCl3 and oxalic acid and complex non-ionic surfactant etc. TEM photomicrographs show that Y2O3 particles are spherical in shape......

to understand the suspension stability as a function of pH, ionic strength, and surfactant concentration. The results show that under the optimal conditions such as pH value of 7 or 9, 0.01 mol/L of ionic strength and around critical micelle concentration(CMC) of surfactant, antibacterial ceramic glaze acquires fine dispersion stability. The adsorption of CPC on ceramic glaze particles......
