Mixed adsorption of hexadecylpyridinium bromide and Triton X surfactants at graphitized carbon black

Characterization of Polymer Carbon Sieves, Graphitized Polymer Carbons and Graphitized Carbon Blacks for Sample Preparation Applications

Adsorption of Lead and Copper by a Carbon Black and Sodium Bentonite Composite Material: Study on Adsorption Isotherms and Kinetics

The efficiency of using a composite of carbon black and sodium bentonite in treating drinking water contaminated with lead and copper ions was analysed. The effects of pH, contact time, concentration and adsorbent dosage using an adsorbent composite of 20 % sodium bentonite and 80 % carbon black were studied. The adsorption data was tested with respect to Langmuir, Freundlich and Temkin iso...

Reversible and irreversible adsorption of surfactants at a hanging mercury drop electrode.

The adsorption-desorption phenomena of surfactants were studied by measuring differential capacity-potential curves in a static solution and differential capacity-time curves in a flowing solution. The surfactants investigated were Aerosol OT, cetylpyridinium chloride, Hyamin 1622, tetrabutylammonium bromide, Triton X-100 and trioctylphosphineoxide. The differential capacity-potential and diffe...

Thermodynamics of adsorption of surfactants at solid-liquid interface

Adsorption of surfactants at interfaces is detenIlined by a number of forces involving electrostatic attraction, covalent bonding, hydrogen bonding, hydrophobic bonding and solvation and desolvation of various species. The extent and type of forces involved vary depending on the adsorbate and the adsorbent and also the composition and other characteristics of the solvent and dissolved component...
