摘要：
An electron spin resonance spectroscopy technique is employed to investigate in situ the kinetics of surfactant adsorption on colloidal particles. Using this technique, it was found that 40% of the adsorption of Aerosol OT at the alumina/cyclohexane interface takes place within 5 s after addition of the surfactant to the suspension. © 1990.
