Method for determining content of photoinitiator in leather product

The invention relates to a method for determining the content of a photoinitiator in a leather product, which is used for detecting the residual quantity of four photoinitiators, namely 3-hydroxy acetophenone, 4-ethoxy acetophenone, 4-hydroxy acetophenone and phenoxy acetophenone, in the leather product. According to the invention, a method combining ultrasonic extraction, solid-phase extraction purification and gas chromatography triple quadrupole mass spectrometry (GC-MS)/MS is established, quantitative and qualitative analysis is carried out on acetophenone photoinitiators in leather products, and the method has the characteristics of simplicity, convenience, quickness and accuracy; the method is high in sensitivity, wide in linear range and good in linearity. 本发明涉及一种皮革制品中光引发剂含量的测定方法，所述测定方法是对皮革制品中的3-羟基苯乙酮、4-乙氧基苯乙酮、4-羟基苯乙酮、苯氧基苯乙酮4种光引发剂的残留量的检测，本发明建立了超声提取、固相萃取净化与气相色谱-三重四极杆质谱(GC-MS/MS)相结合的方法，对皮革制品中苯乙酮类光引发剂的定量和定性分析，本发明方法具有简便、快捷、准确的特点；本发明方法灵敏度高、线性范围宽，线性好。
