摘要

Abstract

A kinetic model fitted by the empirical equation has been proposed to describe the liquid drainage behavior.Rate constants(

) of liquid drainage equation could be obtained from the above empirical equation.In this paper

the stability of the colloidal gas aphrons(CGAs)

the effect of concentrations of sodium dodecyl benzene sulphate(SDBS)

dodecyl trimethylammonium bromide(HTAB) and polyoxyethylene sorbitol anhydride monolaurate(Tween-20)

temperature

stirring speed

stirring time

and various kinds of salts on the

of liquid drainage are further investigated.The results show that the Arrhenius equation can be successfully used to describe the relation between

and absolute temperature(

)

and concentrations of surfactants

stirring speed

stirring time and salinities also have great effect on the

.At last

the CGAs drainage mechanism is explained from analysis of the rate of liquid drainage as a function of time.
