| 摘 要： | 以多壁碳纳米管为吸附材料，建立基质固相分散萃取高效液相色谱法测定牛奶中6种四环素。将多壁碳纳米管、EDTA、草酸和样品研磨混匀装柱，经含甲酸的甲醇洗脱后HPLC多波长紫外检测。6种四环素的检出限0.01～0.03μg/mL，回收率78.7%～105.2%，相对标准偏差小于12%。多壁碳纳米管基质固相分散萃取牛奶中四环素的回收率优于C18，可推广到食品等复杂样品中其他农兽药多残留分析。

| Abstract: | A matrix solid-phase dispersion extraction(MSPDE) method was developed to extract 6 tetracycline antibiotics(TCs) from milk samples using multiwalled carbon nanotubes(MWCNTs) as adsorbent prior to high performance liquid chromatography(HPLC) determination.Milk samples,MWCNTs,oxalic acid,and EDTA were evenly ground and then packed into a glass syringe as dispersion column.The analytes were eluted with methanol containing formic acid,and detected by HPLC with variable wavelength detector at 365 nm.The limits ... |
