Gel for the separation of useful components contained in rhodanate-containing detoxication treated liquid and method of separation using said gel

摘要

The present invention provides a gel having excellent separation ability, operability and a long life, for separating useful components from a rhodanate-containing detoxication treated liquid. The gel consists of a cross-linked polymer with more than 50 weight % of repeating units which are composed of 2,3-dioxypropyl (meth)acrylate or 2,3-dioxypropyl (meth)allyl ether, and whose average particle diameter is more than 10 mu and gel water content is from 30 to 150%. The present invention also provides a method of separation using said gel.
