摘要

<正>Surface modification by physical adsorption of a series of non-ionic surfactants including Tween 20

Tween 40

Tween 60

Tween 80 and Tween 85

was accomplished on polypropylene microporous hollow fiber and flat membranes. The adsorption curve of the membrane surface was analyzed by weight measurements and the typical results showed a two-platform character similarly. Differences in the degree and curve shape of adsorption resulting from such factors as concentration

temperature

as well as water cleaning time were observed for Tween 85 among other Tweens. Attenuated total reflection ?Fourier transform infrared spectroscopy analysis and field emission scanning electron microscopy observation showed that the adsorption of Tween on polypropylene microporous membrane （PPMM） is effective and occurs mainly in the pores of PPMMs at low adsorption amount

and on the membrane surface also at high adsorption value.
