Title:
MIXTURE SEPARATION METHOD AND SEPARATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/133537
Kind Code:
A1
Abstract:
Provided are a mixture separation method and separation device wherein the aggregation of particles contained in the mixture is controlled, the energy necessary of distillation of the supporting liquid is smaller than prior methods, and particles that could not be separated with prior methods can be separated from mixtures containing said particles. The separation method and separation device separate multiple varieties of particles by variety by applying, in a supporting liquid, a magnetic field with a magnetic field gradient on a mixture containing multiple varieties of particles of different substances. Alternatively, the separation method and separation device separate specific varieties of particles from such mixtures. The supporting liquid is an organic solvent solution wherein one or multiple varieties of paramagnetic compounds are solubilized in an organic solvent. The multiple varieties of particles include particles of inorganic salts, organic acid salts, inorganic oxides, and polymer compounds. The organic solvent can be selected from the group consisting of alcohols, ethers, nitriles, ketones, esters, amides, sulfoxides, halomethanes and hydrocarbon solvents.
