Chemistry, Physics and Technology of Surface| Summary: | Sorption of heteropoly acids on the surfaces of cellulose and diethylaminoethylcellulose with molybdovanadophosphoric acid as an example has been studied by UV-VIS, infrared, and MAS-NMR spectroscopy. It has been shown that sorption of heteropoly acid on diethylaminoethylcellulose is substantially higher than that on ordinary cellulose. The mechanism of sorption includes combination of Coulomb and hydrophobic interactions. A scheme of heteropoly acids immobilization has been proposed based on ion exchange on cellulose surface. |
