| 英文摘要 | Multi-template molecularly imprinted materials (mt-MIPs) were prepared by surface imprinting and sealed into porous nylon membrane as micro-solid phase extraction (mu-SPE) device, coupled with high performance liquid chromatography (HPLC) to simultaneously extract and determine five typical chlorophenols (CPs) in leather matrices. By using well-prepared mesoporous silica modified multiwalled carbon nanotubes (MWCNTs@mSi) as supporting materials, and the mixture solution of five CPs as templates, the imprinted layer containing recognition sites of the CPs were formed via free radical polymerization. The as-prepared mt-MIPs were characterized by SEM, TEM, FT-IR and TGA, and the adsorption properties were investigated including static, dynamic and selective adsorption, showing high adsorption capacity of 39.15-71.43 mg g- 1 and rapid mass transfer rate (within 30 min). Parameters affecting the extraction efficiency of membrane protected mu-SPE were optimized, including the type of membrane, amount of adsorbent, type and volume of desorption solvent, desorption time and salt effect. The established mt-MIPs-mu-SPE-HPLC method demonstrated satisfactory linearity of 2.0-200 mu g L- 1, high sensitivity with LODs of 0.17-0.52 mu g L- 1, and high enrichment factor (70.6-144). Consequently, the method was successfully applied to the analysis of five CPs in tannery wastewater, finished leather and wet blue samples. Spike recoveries ranged from 73.00 %-115.2 %, with RSDs of 0.28 %-11.4 %, and matrix interference was examined to be negligible. The developed method proved viable for the simultaneous extraction and quantification of trace CPs in complex leather matrices. |
