Removal of organic solvents from contaminated water by organogels basedon butyl acrylate and ۲-hydroxy methacrylate

In recent years, organic pollutants have caused many environmental problems by polluting water andsoil. Therefore, developing a low-cost, high-efficiency absorbent remains a major challenge.Molecular absorbents, due to their high ability to absorb organic solvents, have been considered toeliminate the risks of leakage and spillage of volatile organic compounds. In this paper, a new set oflipophilic organogels based on poly(۲-hydroxyethyl methacrylate-co-butyl acrylate) was synthesizedusing common radical reactions. The successful synthesis of these organogels was confirmed byFourier transform infrared (FTIR) spectroscopy. The synthesized organogels absorbed a range oforganic solvents with varied dielectric constants from Tetrahydrofuran (THF) to dimethyl sulfoxide(DMSO) (with ε = ۷.۵۸ - ۴۶.۵).
