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表面的吸附层厚度不同，其水链段的增加有利于增大其在水性（煤）表面的吸附厚度。

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处理苯的吸附时，出现折线形的吸附等温线，折线的转折点正好是单层吸附与层吸附的界点。
