Abstract
The adsorption of cationic surfactant cetyltrimethylammonium bromide ( CTAB) from aqueous solution onto carbon black was studied using charge -compensating polyelectrolyte titration for quantitative determination of the surfactant content in solution and X-ray powder diffraction an alysis of air-dried dispersions. Sharp saturation was observed. The sa turated surface concentration of the adsorbed CTAB was found to be the same in the dispersed and air-dried product. Fourier transformed infr ared spectroscopy and extended X-ray absorption fine structure (EXAFS) analyses suggest -CTA(+) and Pr ion sites in the dried product. (C) 1 998 Elsevier Science Ltd.
