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