Abstract: There are several methods for radioactive strontium removal from wastewater. Among those,adsorption is considered to be effective and clean due to its exceptional selectivity,simple operation process and less chemical use. This paper reviewed the latest advances in treatment of ⁹⁰Sr-contaimnated wastewater by adsorption,especially after the Fukushima nuclear accident in 2011. We focused on the research developments on several novel adsorption materials,such as doped metal oxides,nanocarbon materials and metal sulfides. The pros and cons of these materials were analyzed in terms of their synthesises,adsorption properties and practical applications. Furthermore,future research challenges and opportunities were also discussed in the hope of developing clean,efficient and cheap adsorption materials and of exploring their practical application in ⁹⁰Sr-contaminated wastewater treatment.

Key words: waste water, radioactive strontium, adsorption, adsorbent, doped metal oxide
