摘要

•This study investigates the removal of 99TcO4−/ReO4− by the tertiary amine-functionalized adsorbent.•The stable efficient removal of 99TcO4−/ReO4− is achieved in medium–low acid solution.•High concentration of coexisting ions has little effect on 99TcO4−/ReO4− removal efficiency.•XPS and EDS analysis show that anion exchange is the dominant adsorption mechanism.
