功能化聚丙烯纤维及其用于水中苯酚的富集研究
Modification of PP fiber and application for gathering phenol in water
摘要
Abstract
The surface of polypropylene (PP) fiher is grafted polymerization with octadeeyl acrylate (SA) initialed by high energy electron beam. The fiber as filler of solid phase extraction (SPK) is used for enrichment and extraction of phenol in water. The influence of grafting degree and pH value on the adsorption effect of funclional fiber is studied through static adsorption experiments. The injection speed and the eluent volume process are researched 10 obtain the optimized parameter in SPE process. The result shows that, when the phenol solution passes the fiber column with a speed of 10 mlVmin and with 3 mL anhydrous alcohol for eluent, the enrichment capacity of PP fiber for phenol is up to 30 limes, following a excellent recovery ratio at 75%-90%. The results indicate that the PP grafted fiber as solid e.xtractanl could successfully he used to enrichment extraction of trace phenol in water.关键词
