二氧化锆掺杂聚多巴胺纳米复合涂层的制备及其对环境水样中多环芳烃的高效固相微萃取
Fabrication of Zirconium Dioxide-doped Polydopamine Nanocomposite Coating for Highly Efficient Solid Phase Microextraction of Polycyclic Aromatic Hydrocarbons in Environmental Water Samples
摘要
Abstract
Zirconium dioxide(ZrO2)is a suitable solid phase microextraction(SPME)fiber coating due to its high thermal and chemical stability and excellent adsorption.Similarly,polydopamine(PDA)can also be utilized as SPME fiber coating because of its strong oxidation resistance and stability,desired adsorption as well as environmental friendliness.In this work,a novel zirconium dioxide-doped polydopamine(ZrO2@PDA)SPME fiber coating was quickly fabricated on the stainless steel(SS)by cyclic voltammetry(CV)using the etched SS wire as working electrode,a Pt rod as counter electrode and a saturated calomel electrode as reference electrode.Coupled with high performance liquid chromatography-ultraviolet detection(HPLC-UV),the extraction performance of the fabricated SS@ZrO2@PDA fiber was evaluated using typical aromatic compounds of polycyclic aromatic hydrocarbons(PAHs),ultraviolet filters(UvFs),phthalate acid esters(PAEs)and chlorophenols(CPs).The SS@ZrO2@PDA fiber showed excellent extraction capability for PAHs and PAEs,however,poor extraction capability for UvFs and no extraction capability for CPs.Therefore,PAHs were selected as target analytes and the key experimental factors on extraction efficiency were optimized.Under the optimized conditions,good linearity was obtained for the developed SPME-HPLC-UV method with the SS@ZrO2@PDA fiber.The limits of detection(LODs,S/N=3)were 0.018-0.082 μg/L.The developed method was successfully applied to determination of trace PAHs in different actual water samples with recoveries of 86.7%-102.4%and RSDs less than 8.2%.In addition,the fabricated novel fiber was simple to prepare and exhibited high stability,good reproducibility and long service life.关键词
