| titleOfInvention | Semi-interpenetrating network polymer supported membrane, preparation and application for electric membrane extraction |
| abstract | The invention relates to a semi-interpenetrating network polymer supported membrane, preparation and application for electromembrane extraction, and belongs to the technical field of sample pretreatment. The preparation method comprises the steps of soaking the porous polypropylene film in the polyglycol polymer, and then carrying out ultrasonic treatment to promote the blending of the polyglycol polymer and polypropylene so as to uniformly disperse the linear polyglycol polymer into holes of the polypropylene film; and (3) reacting the porous polypropylene membrane blended with the polyglycol polymer for 40-100 h at the temperature of 60-100 ℃, so as to promote the mutually crossing of the polyglycol polymer and the polypropylene to form an integrated cross-linked network, and thus obtaining the semi-interpenetrating network polymer support membrane. The semi-interpenetrating network polymer supported membrane is used for replacing an organic solvent supported liquid membrane in the traditional electric membrane extraction technology, so that the use of an organic solvent is completely eradicated, and the problems of unstable extraction effect and environmental pollution caused by volatilization of the organic solvent are avoided. |
