DYNAMICS OF Sr2+ ION ABSORPTION FROM AQUEOUS SOLUTIONS ON ACTIVATED CARBON CAN-7 

The dynamics of adsorption of strontium ions from aqueous solutions was studied on concentrated solutions of CAN-7 activated carbon, at different lengths of the adsorbent column working layer and at different solution filtration rates. 

The following parameters were determined based on the breakthrough curves of strontium ions from aqueous solutions on CAN-7 activated carbon at the solution filtration rate of 10mL / min: (i) the length of the working layer of the adsorbent column(ii), the length of the inactive layer (iii), the speed of movement of the adsorbent front, and (iv) the travel time of the adsorbate carrying solution through the working layer of the adsorbent. 

Keywords: activated carbon, adsorption, aqueous solutions, dynamic conditions.
