Embodiment 1
[0039] A method for separating oil-water microemulsion based on composite Janus microspheres, comprising the steps of:
[0040] 1) Disperse crescent-shaped polyacrylic acid-polystyrene-polydivinylbenzene Janus microspheres with a particle size of 2.4 μm in ethanol to obtain a Janus microsphere dispersion with a concentration of 10 mg / mL;
[0041] 2) Disperse the magnetic iron ferric oxide nanoparticles in ethanol to obtain a magnetic nanoparticle dispersion with a concentration of 5 mg / mL;
[0042] 3) Mix and stir 20mL of the Janus microsphere dispersion and 10mL of the magnetic nanoparticle dispersion for 12h to obtain a suspension; place the suspension in a centrifuge for separation to obtain a solid precipitate; use the solid precipitate to Washed twice with absolute ethanol, collected by centrifugation, and then dried in vacuum at 50°C to obtain composite Janus microspheres;
[0043] 4) dispersing the composite Janus microspheres in water to obtain a composite Janus micro...
Embodiment 2
[0048] A method for separating oil-water microemulsion based on composite Janus microspheres, comprising the steps of:
[0049] 1) Disperse crescent-shaped polyacrylic acid-polystyrene-polydivinylbenzene Janus microspheres with a particle size of 1 μm in ethanol to obtain a Janus microsphere dispersion with a concentration of 1 mg / mL;
[0050] 2) Dispersing magnetic cobalt oxide nanoparticles in ethanol to obtain a magnetic nanoparticle dispersion with a concentration of 0.5 mg / mL;
[0051]3) 10 mL of the Janus microsphere dispersion and 5 mL of the magnetic nanoparticle dispersion were mixed and stirred for 10 h to obtain a suspension; the suspension was placed in a centrifuge for separation to obtain a solid precipitate; the solid precipitate was used Washed twice with absolute ethanol, collected by centrifugation, and then dried in vacuum at 40°C to obtain composite Janus microspheres;
[0052] 4) dispersing the composite Janus microspheres in water to obtain a composite J...
