Title:
FILTER FOR METAL ION ADSORPTION AND METAL RECOVERY METHOD
Document Type and Number:
Japanese Patent JP2014180644
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a filter for metal ion adsorption excellent in adsorption property and elution property of metal ions, and shape maintenance properties.SOLUTION: There is provided a metal ion adsorption material containing 100 pts.mass of a resin component containing an amine-based polymer (A) having an amino group or a tertiary ammonium group in a repeating unit of 10 to 40 mass% and a hydrophilic polymer (B) having no amino group and no tertiary ammonium group in a repeating unit of 60 to 90 mass%, and 0.10 to 10 pts.mass of fine particle (C), and an average particle diameter of the fine particle (C) is 0.012 to 20 μm. There is also provided a filter for metal ion adsorption containing a binder of 3 to 10 pts.mass based on 100 pts.mass of the metal ion adsorption material.
