Preparation of Interpenetrating Network Polyvinyl Alcohol Composite Coatings for Solid-phase Microextraction
摘要
Abstract
PVA/SiO2 composite coatings which have the interpenetrating organic and inorganic cross-linked network were prepared by repeated freezing-thawing and sol-gel techniques. The structure and characterization of the composite membrane were determined by FTIR, TGA, SEM and gas chromatography. The composite coatings have good thermal stability (Td>300℃ ) and good adherence activity that they are difficult shedding from coated glass or quartz fiber surface by chemical bonds. The performance of the coatings was tested by extraction of 1 -propanol, 1 - butanol, amyl alcohol and toluene. The fiber coatings proved to be selective for polar compounds containing hydroxyl groups. The relative standard deviation( RSD, n = 3) was less than 5%.关键词
