卷烟接装纸、成型纸中荧光增白剂ABP、VBL的HPLC测定

Determination of Fluorescent Whitening Agents in Tipping Paper and Plug Wrapper with HPLC

摘要

摘要: 采用高效液相色谱法同时检测了64个卷烟滤嘴成型纸、接装纸样品中的荧光增白剂ABP、VBL含量。即先用紫外灯照射纸样品,而后用N,N-二甲基甲酰胺提取显示荧光的样品,提取液经Alltima C₁₈柱(150 mm×4.6 mm×5 μm)色谱分离和甲醇水(体积比45:55,流速1.0 mL/min)混合液洗脱,在波长435 nm下检测。结果显示:①ABP、VBL的检出限分别为0.10、0.15 ng/mL,平均回收率101.0%~102.1%、102.0%~104.2%,RSD 0.66%~2.48%、0.89%~1.84%;②60个纸样在紫外光下没有荧光;③4个有荧光的纸样中均未检出ABP,而都检出了VBL,其中,1个为接装纸样品,3个为成型纸样品。该法适用于批量卷烟滤嘴成型纸和接装纸中荧光增白剂ABP、VBL的同时测定。

Abstract: The fluorescent whitening agents,ABP and VBL,in 64 samples of tipping paper and plug wrapper were determined with HPLC.The samples were irradiated by UV-lamp,and the samples which fluoresced were extracted with N,N-dimethylformamide.The resultant extract was passed through an Alltima C₁₈ column(150 mm×4.6 mm×5 μm) using methanol-aqueous solution (45:55,v/v) as mobile phase at a flow rate of 1.0 mL/min,and detected at the wave length of 435 nm.The results showed that:1) the average recoveries of ABP and VBL were 101.0% to 102.1% and 102.0% to 104.2% with RSD of 0.66% to 2.48% and 0.89% to 1.84% at detection limits of 0.10 and 0.15 ng/mL,respectively;2) 60 samples did not fluoresce under UV-lamp;3) VBL was detected in the other 4 samples which fluoresced,while ABP was not;among the 4 samples,1 was tipping paper and 3 were plug wrapper.The method is suitable for the simultaneous determination of ABP and VBL in batches of plug wrapper and tipping paper samples.
