摘要： The invention provides a method for producing a purified carbon black by removing metal from the aqueous dispersion of carbon black, wherein the metal is removed by bringing the aqueous dispersion of carbon black into contact with at least one organic acid selected from the group consisting of glycolic acid, ascorbic acid and malonic acid. The invention can provide a method for producing the purified carbon black where the metal components such as iron and the other metals contained as the impurities in carbon black can be reduced.
