吸附层

But for benzene, when treated with SDM-A there was a turning point in its adsorption isotherm, which corresponding to the dividing point between monomolecular and multimolecular layer adsorption.

在用SDM-A处理苯时，出现折线形等温线，折线转折点正好是单子层与多子层点。

It is favorable for the increase of the adsorption film thickness by increasing the lyophobic chain.The determination of adsorption film thickness verifies the validity of the modification result.

木钠及改性木钠在疏水性和亲水性固体表面层厚度不，子疏水链段增加有利于增大在疏水性（煤）表面厚度。
