Method for producing zinc salt aqueous solution with reduced thallium content, zinc oxide production method, and zinc oxide

摘要

Problem to be solved: to provide a method of manufacturing a zinc salt aqueous solution having reduced thallium content by a simple method. The present invention also provides a method of producing zinc oxide using the zinc salt aqueous solution and a zinc oxide having very little thallium content.Solution: the zinc salt aqueous solution production method of the present invention includes a contact step for contacting a zinc salt aqueous solution containing thallium as an impurity element and at least one adsorbent selected from the group consisting of zeolite, activated white soil, activated carbon, and cation exchange resin.No selection
