| dc.description.abstract | A study was conducted to understand the mechanism of adsorption kinetic that is effective in removal of Po-209 by clinoptilolite, a natural zeolite, from aquatic environments. Studies of the adsorption kinetics of Po-209 were carried out by interacting zeolite with Po-209 at different time intervals. Experimental polonium adsorption data obtained in our previous article were applied to some known kinetic models such as pseudo-first order, pseudo-second order, Elowich, Bangham, Homogeneous particle diffusion and Shell step models. The data obtained from the models revealed that the rate-limiting step is more compatible with the pseudo-second order model, which is based on the assumption that chemical sorption. According to the results obtained, the calculated the amount of Po-209 adsorbed at equilibrium (q(e)) and the equilibrium rate constant of pseudo-second-order sorption (k(2)) were found to be 0.3302 ng g(-1), - 4.4 x 10(-5) ng g(-1) min(-1), respectively. | |
