Removal of emulsion droplets by immobilization in calcium alginate gel

A novel technique utilizing particle immobilization in hydrogels has been proposed for a solid-liquid separation of difficult-to-filter colloidal suspensions. Fundamental aspects of this process are investigated using oil in water (O/W) emulsion as colloidal materials. A mixture of alginate aqueous...
