Environmental Friendly

Analytical pretreatment has become environmental-friendly because of material science assistance. In stir bar sorptive extraction (SBSE), a coating is typically used to isolate and preconcentrate organic compounds in aqueous samples. Here, a translucent coating based on polydimethylsiloxane and phenyltriethoxysilane was prepared by a sol-gel method. Characterization tests showed that the coating was homogeneous, relatively polar, and both thermally (< 400 °C) and chemically stable. Coated stir bars were evaluated in the SBSE experiments. Benzene derivatives were successfully extracted/preconcentrated from aqueous solutions and environmental waters. Furanic derivatives and antibiotics were moderately extracted from water, but they were extracted from isooctane.
