Filter for refining plating liquid and adsorbent for purification of plating liquid

摘要

Problem to be solved: to provide an activated carbon containing filter for purifying the plating solution capable of efficiently removing the decomposition product produced from the additive.A filter for purifying plating liquid according to one aspect of the present invention isContains an adsorbent consisting of activated carbonA molded body 6 having an iodine adsorption amount per unit mass of 930 to 1300 mg / G is providedChloride ion concentration is 6.0 to 9.0 mg / LPH 6.9 to 7.5Electrical conductivity is μ The concentration of chloride ion of filtered water after filtration of raw water, which is s / cm, was filtered for 1 minuteIt is less than the chloride ion concentration of the raw water.Diagram
