Method for simultaneously determining 15 fluorescent whitening agents in food contact paper product by high performance liquid chromatography-fluorescence method

The invention discloses a method for simultaneously determining 15 fluorescent whitening agents in food contact paper products through a high performance liquid chromatography-fluorescence method, and the 15 fluorescent whitening agents are respectively the fluorescent whitening agents C.I.368, C.I.367, C.I.135, C.I.378, C.I.71, C.I.220, C.I.199A, C.I.24, C.I.134, C.I.113, C.I.199B, C.I.393, C.I.351, C.I.184 and C.I.140. The method has the advantages of being simple and convenient to operate, good in repeatability and high in sensitivity. 15 ionic and non-ionic fluorescent whitening agents which are widely used at present and meet the requirements of laws and regulations and related standards can be measured at the same time. 本发明公开了一种高效液相色谱-荧光法同时测定食品接触纸制品中15种荧光增白剂的方法，15种荧光增白剂分别为荧光增白剂C.I.368、C.I.367、C.I.135、C.I.378，C.I.71，C.I.220、C.I.199A、C.I.24、C.I.134、C.I.113、C.I.199B、C.I.393、C.I.351、C.I.184、C.I.140，该方法具有操作简便，可重复性好，灵敏度高的优点，实现对目前广泛使用且受到法规和相关标准要求的15种离子型和非离子型荧光增白剂的同时测定。
