液相色谱-串联质谱法测定纺织品中7种荧光增白剂
Determination of 7 kinds of fluorescent brightener in textiles by high performance liquid chromatography-tandem mass spectrometry
摘要
Abstract
A method of the determination of seven ionic fluorescent whitening agent residues in textile-was established by high performance liquid chromatography-tandem mass spectrometry. The sample was ex-tracted with water-methanol (25/75), ultrasonic extraction of 30 min in water bath at 70 ℃. The gradient elu-tion separation was carried out on the Hypersil GOLD-C18 column with the aqueous solution of 10 mmol/L ammonium formate and methanol as the mobile phase. The mass spectrum acquisition mode was the electro-spray negative ion mode. The linear relationship of the 7 kinds of ion FWAs was good in a certain mass con-centration range, and the correlation coefficient was more than 0.99. The recovery of 7 kinds of anions FWAs was 86.0％～96.0％, and the relative standard deviation (RSDs) was 2.7％～6.4％. This method had the advan-tages of simple, high sensitivity and short analysis time, and had certain practical application value.关键词
