高效液相色谱/荧光检测法测定纺织品中7种阴离子荧光增白剂
Determination of Seven Anionic Fluorescent Whitening Agent Residue in Textile by High Performance Liquid Chromatography
摘要
Abstract
A sample pretreatment coupled to high performance liquid chromatography with fluorescent detector( HPLC/FLD)method was developed for the determination of 7 anionic fluorescent whitening agents(FWAs),including fluorescent brightener 353(MST),2,2’-(1,2-ethenediyl)bis(5-((4-(bis(2-hydroxyethyl)amino)-6-((4-sulfophenyl)amino)-1,3,5-triazin-2-yl)amino)-benzenesulfo-nicacitetrasodiumsalt( ABP),disodium 4,4’-bis[(4-anilino-6-hydroxyethylamino-1,3,5-triazin-2-yl)amino ] stilbene-2,2’-disulphonate( VBL ),2,2’-(( 1,1’-biphenyl )-4,4’-diyldi-2,1-ethenediyl)bis-benzenesulfonicaci(4BK),2,5-bis(5-tertbutyl-2-benzoxazlyl)phiophene( CBS), disodium 4,4’-bis[(4-anilino-6-morpholino-1,3,5-triazin-2-yl)amino]stilbene-2,2’-disulpho-nate(CXT)and sodium 4-[3-(4-chlorophenyl)-4,5-dihydro-5-phenyl-1H-pyrazol-1-yl]benzenesul-phonate(WG)in textile. The samples were extracted with water-methanol(25 : 75),and directly qualitatively and quantitatively analyzed by HPLC/FLD. The separation of target compounds was per-formed on a Phenomenex Gemini 5u C18(150 mmí4. 6 mm,5 μm)column by gradient elution u-sing acetonitrile-water( containing 2. 5 mmol/L ammonium acetate)as mobile phase. The calibra-tion curves of 7 anionic FWAs showed good linearities with correlation coefficients not less than 0. 999 6. The limits of quantitation(LOQs,S/N=10)were in the range of 0. 1-5. 0 mg/kg. The recov-eries of 7 anionic FWAs in negative cotton and wool at three spiked levels ranged from 89. 5% to 98. 9% with relative standard deviations( RSDs)of 2. 4% -4. 7% . With the advantages of simplici-ty,high sensitivity and time-saving,this metsod has a certain practical value.关键词
