COLLOIDAL DISPERSION LIQUID OF METAL PARTICLE OR METAL COMPOUND PARTICLE, AND METHOD FOR TESTING INTEGRITY OF SEPARATION MEMBRANE

摘要

PROBLEM TO BE SOLVED: To provide a colloidal gold dispersion liquid with stabilized dispersion state and a method for evaluating a fractional layer of a separation membrane.;SOLUTION: The colloidal dispersion liquid of metal particles or metal compound particles includes: (1) metal particles or metal compound particles with an average particle diameter of 10 to 30 nm; (2) a water-soluble dispersant containing an SH group; (3) proteins; and (4) a solvent. The method provided is for testing the integrity of a separation membrane using the colloidal dispersion liquid.;COPYRIGHT: (C)2011,JPO&INPIT
