Common agro-waste, potato peels were used to study the efficacy of adsorption of long-lived radioisotopes, 133Ba (T1/2= 10.54 a) and 134Cs (T1/2 = 2.06 a) as a precursor of fission products 140Ba (T1/2 = 12.75 d) and 137Cs (T1/2 = 30.07 a). At optimized condition of pH = 3, high Kd value > 3 × 104 cm3 g−1 was observed for Ba, when 60 mg dried potato peel was used as sorbent-material for adsorption from a binary aqueous solution containing 133Ba and 134Cs. Cs showed low Kd values across the entire pH range. The bio-sorbent could effectively uptake ~ 99% of 133Ba and ~ 48% of 134Cs at the best condition.
