Title:
SEPARATION MEMBRANE AND SEPARATION MEMBRANE MODULE, BOTH IMPROVED IN OXIDATION RESISTANCE, AND THEIR PRODUCTION METHODS
Document Type and Number:
Japanese Patent JP2005081241
Kind Code:
A
Abstract:

To provide a separation membrane and a separation membrane module, both prevented from degradation of membrane performance and from oxidation degradation even in a long-term storage.

In a long-term storage, the oxidation degradation of the membrane causes the degradation of the membrane and membrane performance to proceed, and the proceeding of the degradation relates to a peroxide in an eluted substance test solution and a test solution pH. Contrary to a general concept, by causing a metal ion known as an oxidation catalyst to coexist in forming the film, the peroxide is eliminated, improving the oxidation resistance.
