Abstract:

This paper first put forth a measurement of the dynamic surface tension (DST) of the reactive surfactant sodium dodecyl allyl sulfosuccinate (ELENIMOL JS-2) by means of the maximum bubble-pressure method. Next ,the effects of the ELENIMOL JS-2 concentration , the temperature and the electrolyte on the DST were investigated.Then , the parameters describing the DST were calculated. Finally , according to Word-Tordai equation , the adsorption kinetics of aqueous ELENIMOL JS-2 solution was presented. The results show that the adsorption process fol-lows a pure diffusion step at the beginning of the adsorption , obeys the mixed diffusion-kinetic adsorption mechanism during the adsorption process , and is finally controlled by a pseudo-diffusion step.

Key words: sodium dodecyl allyl sulfosuccinate, dynamic surface tension, adsorption kinetics, maximum bubblepressure method, reactive (polymerizable) surfactant
