Sorption characteristics and performance of an acid dye on a gel-type weak anion exchanger in a finite bath

The sorption behaviour of carminic acid on a gel-type weak anion exchanger was evaluated in a finite bath. Equilibrium and kinetic studies were employed to characterise the system. Adsorption isotherms were found to follow the Langmuir expression. Concentration-time profiles were obtained in a stirr...
