Abstract
The invention relates to the field of reagent impurity removal, and discloses a method and a system for removing trace iron ions in an alcohol reagent, and the method comprises the following steps: (1) mixing the alcohol reagent with water, so that the water content in the alcohol reagent to be treated is more than 7wt%; (2) in the micro-nano bubble generating device, contacting the alcohol reagent to be treated with an oxidizing agent, and carrying out oxidation reaction to obtain a material after the oxidation reaction; and (3) carrying out membrane separation treatment on the material after the oxidation reaction to obtain the alcohol reagent without iron ions. The method has the advantages of low energy consumption, short process route, high removal efficiency, low cost and the like, and the content of iron ions in the alcohol reagent can be controlled below 0.1 ppb.
