14 p, 598.2 KB Studies on the adsorption of dyes to kaolinite / Harris, Rodney G. (Brewing Research International) ; Johnson, Bruce B. (La Trobe University. Colloid and Environmental Chemistry Laboratory) ; Wells, John D. (La Trobe University. Colloid and Environmental Chemistry Laboratory)
The strong adsorption to kaolinite of four polyaromatic, cationic dyes (9-aminoacridine, 3,6-diaminoacridine, azure A and safranin O), which adsorb much less to alumina or silica, was investigated by means of acid-base titrations, measurements of adsorption at varying pH and dye concentration, and by ATR-FTIR spectroscopy.

7 p, 456.7 KB Competitive adsorption of Cd and dyes to kaolinite / Harris, Rodney G. (Brewing Research International) ; Johnson, Bruce B. (La Trobe University. Colloid and Environmental Chemistry Laboratory) ; Wells, John D. (La Trobe University. Colloid and Environmental Chemistry Laboratory)
The competitive adsorption to kaolinite between Cd(II) and four polyaromatic dyes (9-aminoacridine, 3,6-diaminoacridine, azure A and safranin O) was studied in 5 mM KNO at 25°C. Under these conditions, Cd adsorbs to the silica face of kaolinite between about pH 4 and 6. [...]

Colloid and Environmental Chemistry Laboratory) ; Angove, Michael J. (La Trobe University. Colloid and Environmental Chemistry Laboratory) ; Johnson, Bruce B. (La Trobe University. Colloid and Environmental Chemistry Laboratory)
Simple extended constant capacitance surface complexation models have been developed to represent the adsorption of polyaromatic dyes (9-aminoacridine, 3,6-diaminoacridine, azure A and safranin O) to kaolinite, and the competitive adsorption of the dyes with Cd. [...]
