The novelty of this article is focusing on the synthesis method of microfluidic technology. Microfluidic technology occupies high position in product control for the controllable size, structure, component and morphology. The key part of microfluidic equipment is the chip. The continuous phase was pumped into microfluidic chip to sheer dispersed phase at the cross aisle. Dispersed phase necked first under extrusion and shear force, and then it drew and broke into a spherical microsphere finally for its own surface tension. The microsphere flowed through outlet steadily and uniformly into a beaker filled with solidification bath for crosslinking. These microspheres would become impact, stable and plastic after crosslinking. Prepared microspheres were extremely monodispersed, uniform-sized, highly spherical and smooth-faced. The CV value of these prepared microspheres in our work is 1.52%, greatly lower than those CV of microsphere prepared with membrane emulsification or suspension polymerization approaches which were usually about 10%. High monodispersed microspheres could separate out of medium completely or be convenient to handle. The adsorption behavior of these microspheres towards copper (II) and main influencing factors on adsorption performance had been investigated by batch experiments. These microspheres also showed excellent adsorption selectivity and renewability. All these researches provided a brand new direction for preparing highly comprehensive performance sorbent via microfluidic technology.[展开] ...
