Document Type and Number:
WIPO Patent Application WO/2020/138051
Kind Code:
A1
Abstract:
A plating solution purification filter according to one aspect of the present invention comprises a molded body that contains an adsorbent constituted by activated carbon and that has an iodine adsorption capacity per unit of mass of 930 to 1,300 mg/g. When raw water having a chloride ion concentration of 6.0 to 9.0 mg/L, a pH of 6.9 to 7.5, and an electrical conductivity of 90 to 130 μS/cm is filtered for one minute, the collected filtered water has a chloride ion concentration that is equal to or less than the chloride ion concentration of the raw water.
