Rezumat | |||||||
Inflection points of strontium ion adsorption isotherms on CAN-7 and oxidized CAN-8 activated carbons were studied. The causes of inflection points on strontium ion adsorption isotherms on CAN-7 and oxidized CAN-8 activated carbons, obtained in the laboratory from walnut shells were identified. Studies have shown that the bonds between Sr(OH)+ and strong and weak carboxylic groups in the micropores and supermicropores of CAN-7 activated carbon are stronger than those in mesopores and macropores. The differential heating curve (DTA) of strontium ions adsorbed on CAN-7 has two thermal effects: one endothermic and the other exothermic. |
