Description

The adsorption of 137Cs 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 137Cs 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 137Cs 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. (author)
