Abstract

The composite adsorbent prepared by mixing of polyacrylonitrile and clinoptilolite was used for investigating the adsorption behaviour of ²²⁶Ra in column system. The effective parameters like initial activity concentration, pH of the solution, contact time and temperature for adsorption behaviour of ²²⁶Ra were studied. Adsorption efficiency of ²²⁶Ra on composite adsorbent from aqueous solution was determined to 98.73 ± 0.59 % at pH 5.0 and 30 °C in a short time. The isotherm models were studied to evaluated adsorption characteristics of ²²⁶Ra onto composite adsorbent. The thermodynamic parameters were showing that the processes for ²²⁶Ra were exothermic. Adsorption kinetics of the radium is also studied.
