Rezumat

S-a studiat dinamica adsorbţiei ionilor de stronţiu din soluţii apoase pe cărbunele activ CAN-7 concentrat la diferite lungimi ale stratului de lucru al coloanei cu adsorbant şi la diferite viteze de filtrare a soluţiei. În baza curbelor de străpungere a ionilor de stronţiu din soluţii apoase pe cărbunele activ CAN-7 la viteza de filtrare a soluţiei 10 mL/min, s-a determinat: lungimea stratului de lucru al coloanei cu adsorbant, lungimea stratului inactiv, viteza de mişcare a frontului adsorbţional şi timpul de parcurs al soluţiei cu adsorbat prin stratul de lucru al adsorbantului.

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.
