吸附层

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.

木钠及改性木钠在水性和亲水性固体层厚度不同，其分子水链段增加有利于增大其在水性（煤）厚度。

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分子层与多分子层分界点。
