| Abstract: | The equilibrium and kinetic behaviour of weakly acidic resin (WAR) with alkali and weakly basic resin (WBR) with acids have been studied by many research teams. But little work is reported in literature regarding equilibrium and kinetic behaviour of mixture of WAR and WBR.
In the present study, detailed analysis of equilibrium and kinetic behaviour of mixed resins with sodium chloride has been undertaken. From equilibrium studies, no adsorption is observed taking place, when salt solution is brought in contact with WAR or WBR individually; however adsorption is observed taking place, when salt solution is brought in contact with the mixture of WAR and WBR. The salt uptake depends on the concentration of salt solution, the amounts of individual ion-exchange resins as well as their proportion.
Mixture of resins and salt solution has three phases interacting with each other and a number of resistances can influence salt uptake rate either individually or in combination. A series of ... |
