METHOD FOR DEMULSIFICATION OF WATER-IN-OIL TYPE EMULSION USING ELECTRIC FIELD

摘要

PROBLEM TO BE SOLVED: To solve the problem of conventional demulsification methods using electric field that electrodes for generating electric field have to be disposed in a container and it is difficult to dispose the electrodes in the case of small containers to be used in biochemical fields, and that a solution is contaminated with electrode materials or a solution is electrolyzed because the electrodes are always brought into contact with the solution in the conventional methods.;SOLUTION: Demulsification of a water-in-oil type emulsion can be carried out in a non-contact manner by applying electric field, preferably alternating current electric field, from the outside of a container. That is, electric field generated by applying voltage to electrodes set in the outside of a container made of a dielectric is applied to the water-in-oil type emulsion kept in the container to carry out demulsification.;COPYRIGHT: (C)2008,JPO&INPIT
