Abstract: 

Biosorption of stable strontium ( ) and strontium-90 ( , radioactive) by Cysroseira indica brown alga was studied in this research. The optimum absorption pH is 9±0.3 and the highest absorption capacity was seen after 6 hours of contact. Based on Langmuir isotherm, the maximum bisorption capacity was 26.67 mg/g.dry-wt and 10526 Bq/g-dry.wt. Meanwhile, Langmuir coefficients were 0.017 and 0.00006 for and, respectively. Increasing concentration and activity and using more biomass caused an increase in and removal. The dynamic capacity was 14.17 mg/g-dry.wt (:160.97mL/g) in the test column. There is no change in the biomass absorption capacity after 5 times of absorption and desorption experiments using CaCl2, NaCl, CH3COOH and EDTA.
