The adsorption of Cs-137 by a carbonized paper sludge (PSC) was studied using the original and its modified form (PFC-PSC) by impregnating with 1 % potassium ferrocyanide. The distribution coefficient of PSC decreases with increasing Cs+ concentration in Cs-137 solutions whereas that of PFC-PSC is highest at around and lower than 60 Bq ml(-1). The Freundlich constant of PFC-PSC is much higher than that of PSC, suggesting that the Cs-137 affinity of the former is higher than the latter. The pseudo second order rate constant of PSC decreases but that of PFC-PSC increases with decreasing Cs+ concentration.
