The invention relates to a method for removing trace anions from an alcohol organic solvent by a resin method. The method comprises the following steps of: (1) selecting an exchange resin, namely determining to use a gel type acrylic acid series anion exchange resin; (2) pretreating the resin, namely a, soaking the new gel type acrylic acid series anion exchange resin by using diluted sodium chloride (NaCl); b, washing the exchange resin repeatedly with deionized water; c, soaking the exchange resin by using diluted sodium hydroxide (NaOH); d, washing the exchange resin with the deionized water again until the pH value is about 7.5 to 8; and e, dehydrating by using a centrifugal machine and drying; and (3) injecting the alcohol organic solvent with the trace anions to be removed into a treated resin column so as to remove 50 milliliters of the alcohol organic solvent which flows out firstly, and collecting the alcohol organic solvent which flows out finally to obtain the product. By the method, the quality indexes of an electronic pure developing solution F6 product are met, wherein chloride, nitrate and nitrite are less than 0.03 mg/L (38ppb), and sulfate is less than 0.05 mg/L (63ppb).
