Conclusions

The polymer adsorbent under investigation includes the macroporous, hypercrosslinked, and also functional polymers. The sorption of organic compounds by porous copolymers of different porous structure and polarity with laboratory and commercial samples was compared. The sorption capacity of hypercrosslinked copolymers is up to five times higher than that of macroporous samples. The presence of micropores and lipophilicity of adsorbate and adsorbent positively affect adsorption. Interaction by dispersion forces characterised the physical adsorption of adsorbate molecules and adsorbent. Polymer adsorbents are superior to the carbonaceous adsorbents in sorption of organic compounds and simply desorption.

The methacrylate copolymers bearing ethyleneamine groups have higher adsorption capacities due to the Lewis acid-base interaction between the phenolic compounds and the tertiary amino groups on the polymer matrix. The phenols are more strongly sorbed on the more polar metha-crylate functional copolymers than on styrene-divinylbenzene copolymers. The adsorbate adsorption increased with the increasing polarity of adsorbate.
