Distribution peculiarities of nonionic surfactant Triton X-100 in system quartz-water-cyclohexane at preferential wetting


Distribution of nonionic surfactant Triton X-100 (TX-100) on solid surface at preferential wetting of quartz by aqueous solutions of TX-100 in cyclohexane environment was investigated by radioactive label and wetting methods. It was established that surfactant adsorbes on quartz surface mainly in three-phase contact line when one’s concentration in water is small. After concentration increase adsorption of TX-100 on solid surface occurs from liquid phases both. Influence of definition character of TX-100 on kinetics of contact angle of preferential wetting formation was demonstrated.
