The adsorption of ions from NaCl, dodecylamine-HCI (DAHCl) or dodecyl-NaSO_4 (SDS) solution on the glass particles, whose surface have been treated, was studied by streaming potential method. These surface treatments were done either by coating with dodecylamine, cholesterol, lauric acid, or dodecano1 to form a layer of about 0.2 μ in thickness, according to the fusion-diffusion-cooling method, or by treating with trimethylchlorosilane (TMCS) in benzene solution. According to the results of these experiments, the adsorbed amount of ions in DAHCl solution was the most in the case of g1ass particles treated with TMCS and, in SDS solution, glass particles coated with dodecylamine. The adsorbed amount was the least in the case of untreated glass particles in SDS solution. These results were explained by competitive influence of electrostatic interaction and hydirophobic interaction.
