摘要： Provided is an apparatus for producing a non-aqueous electrolytic solution capable of easily performing purification treatment by removal of acidic impurities such as hydrogen fluoride contained in a non-aqueous electrolytic solution.
The apparatus for producing a non-aqueous electrolytic solution comprises an ion exchange unit accommodating a weakly basic anion exchange resin through which an alkali metal salt electrolyte-containing solution having the alkali metal salt electrolyte dispersed in an carbonate ester is passed to obtain the non-aqueous electrolytic solution, wherein the weakly basic anion exchange resin has a styrene-based resin as substrate and an amino group as weakly basic anion exchange group.-

摘要： Provided is a method for producing a chelate resin, wherein a highly pure treatment liquid can be obtained by reducing the amount of metal impurities in a to-be-treated liquid containing metal impurities. The method for producing a chelate resin comprises a purification step for purifying a to-be-purified chelate resin by bringing the chelate resin into contact with at least 5 wt % of a mineral acid solution containing 1 mg/L or less of metal impurities, wherein the total amount of metal impurities eluted when 3 wt % of hydrochloric acid is passed through the purified chelate resin in an amount equal to 25 times the amount of the chelate resin by volume ratio is 5 μm/mL-R or less.
