摘要：

通过反复冷冻-解冻和溶胶-凝胶方法制备了聚乙烯醇/SiO2有机/无机双交联网络互穿的固相微萃取涂层, 并利用红外光谱(FTIR)、 热重分析(TGA)、 扫描电子显微镜(SEM)和气相色谱(GC)等方法对该涂层进行了结构及性能表征. 该固相微萃取涂层具有很好的热稳定性(Td>300 ℃), 通过化学键合作用于玻璃或石英纤维表面, 稳定性好, 不易脱落. 对正丙醇、 正丁醇、 异戊醇和甲苯进行萃取, 结果表明, 该纤维涂层对带有羟基的极性物质有很好的选择性, 并且相对标准偏差(RSD, n=3)小于5.0%.

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%.
