SORPTION OF APOLAR LIQUIDS BY NATURAL HIGH MOLECULAR COMPOUNDS

The modern technologies of the adsorption processes are searching new, ecologically friendly adsorbents as natural polymers – chitin and chitosan. Chitin chitosan have high ability in relation to mineral oils, dyes, alcohols, phenols heavy metals. basic sources shells crustacean biomass fungus` mycelium. provides mechanical strength structure without rigid bonds between microfibrilles, that allows keep certain elasticity a cellular wall. submitted researches devoted studying activity received from organic polutants. It was shown use origin sorbents is worthy alternative synthetic sorbents. Natural advantages due environmental friendliness, safety biodegradability. has been experimentally proven investigated absorb pollutants with an efficiency up 98%. nature polymer method its introduction affect effectiveness sorption process. Sorption can be described using Langmuir Freundlich equations. In order clarify mechanism, temperature dependence process studied. all cases, vaseline oil decreases increasing temperature, which suggests physical mechanism sorption. occurs dispersion interaction. Hydrophobic interactions molecules substances non-polar regions macromolecules make contribution studied substances. effective capacity explained not only by chemical properties, developed micropores, but also adding sorbent. Apolar liquids sorbed hydrophobic interaction, forms hydrogen bind polar components composition. pollutants, surface-active substances, metals, renewability biological decomposition allow it considered sufficiently practically universal
