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.%建立了液相色谱-串联质谱法测定纺织品中7种荧光增白剂残留量的检测方法.样品经水/甲醇(25/75)70℃水浴中超声提取30 min,用Hypersil GOLD-C18色谱柱进行分离,以10 mmol/L甲酸铵水溶液与甲醇为流动相进行梯度洗脱分离.质谱采集模式为电喷雾负离子模式.7种离子FWAs在一定质量浓度范围内线性关系良好,相关系数均大于0.995,不同添加水平下,7种阴离子FWAs的回收率为86.0％～96.0％,相对标准偏差(RSDs)为2.7％～6.4％.该方法简单、灵敏度高、分析时间短,具有一定的实际应用价值.
