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.
