Abstract

The Am(III) adsorption from very dilute aqueous solutions on polyethylene was studied as a function of the pH value, the composition of dissolved salts and the presence or absence of adsorbent SiO2. It was found that the Am(III) adsorption on polyethylene is decreased with increasing H+ concentration and dissolved salt concentrations and in the presence of SiO2 as an adsorbent. The mechanisms of Am(III) adsorption on polyethylene were discussed. Based on the observations in this paper, extreme care is necessary to minimize and correct the Am(III) adsorption on the container walls in order to improve the accuracy of Am(III) distribution coefficient (Kd) between a solid and an aqueous solution.
