HPLC/FLD测定聚酯纤维纺织品中9种非离子荧光增白剂
Determination of nine non-ionic fluorescent whitening agent residues in polyester fibre textile by HPLC/FLD
摘要
Abstract
A sample pertreatment coupled to high performance with fluorescent detector (HPLC/FLD) method was developed for determination of nine non-ionic fluorescent whitening agents, including 1,2-bis(5-methyl-2-benzoxazole)ethylene (DT), 7-diethylamino-4-methylcoumarin (SWN), 2,2′-(2,5-thiophenedi⁃yl)bis[5-(1,1-dimethylethyl)-benzoxazol] (OB), 2-[4-[2-[4-(2-benzoxazolyl)phenyl]ethenyl]phenyl]-5-methyl-benzoxazol (KSN), 1,4-bis(2-cyano styryl)benzene (ER-Ⅰ), 1-(2-cyano styryl)-4-1-(2-cyano styryl)-4-(4-cy⁃ano styryl) benzene (ER-Ⅱ), 2,2′-(1,4-naphthalenediyl)bis-benzoxazol (KCB), 4,4′-bis[2-(2-methoxyphenyl) ethenyl]-1′-biphenyl (OB-Ⅰ), 2,2′-(1,2-ethenediyldi-4,1-phenylene)bis(5-methyl-benzoxazol) (OB-Ⅱ) in textile. The sample was extracted with xylene and concentrated, and then qualitatively and quantitatively ana⁃lyzed by HPLC/FLD. The separation of target compounds was performed on a phenomenex Gemini 5u C18 (150 mm × 4.6 mm,5 μm) column by gradient elution using acetonitrile/ammonium acetate solution (containing 2.5 mmol/L ammonium acetate) as mobile phase. The correlation coefficients of nine kinds of non-ionic fluo⁃rescent whitening agents was not less than 0.999 3. The limits of quantification of the nine compounds (LOQs, S/N=10) were 0.70~0.95 mg/kg. The average recoveries of the nine compounds ranged from 83.0% to 100%with the relative standard deviations (RSDs) of 4.0%~8.8%. The method was simple and accurate, which had a certain practical valve.关键词
