Abstract
This study investigated removal of radionuclides (Cs, Sr) in surface water by coagulation and precipitation. Jar tests were conducted with various chemical and natural coagulants to remove the stabilized radionuclides ($^{133}Cs$, $^{88}Sr$). Chemical coagulants included aluminum sulfate, poly aluminum chloride, and poly aluminum hydroxide chloride silicate (PACS); natural coagulants (minerals) included illite and zeolite. Chemical coagulant alone could achieve removals of Cs and Sr less than 10%; The removals increased up to 23.1% for Cs and 17.8% for Sr with addition of poly-dimethyldiallylammonium chloride (polyDADMAC) along with the chemical coagulants. Compared with chemical coagulants, natural coagulants (minerals) could achieve higher removals of Cs and Sr. Addition of zeolite along with PACS and polyDADMAC increased the removal rates up to 36.9% for Cs and 17.1% for Sr.
