Effect of Temperature on the Adsorption of Some Dyes on Kaolinite
1968
Zenodo
Preserved Fulltext
The adsorption of cationic dyes viz., crystal violet, malachite green and methylene blue was measured on kaolinite (<2 0µ. average size fraction) at three different temperatures. The amount of crystal violet and malachite green adsorbed increased with temperature but that of methylene blue remained constant within the limits of experimental error. The heats of adsorption calculated from the isotherms varied between -2.6 and -8.7 K. Cals/mole. The heats of adsorption attain a maximum at a
