摘　　要：建立一种同时测定水性涂料产品中烷基酚聚氧乙烯醚(辛基酚聚氧乙烯醚和壬基酚聚氧乙烯醚(n=2~16))含量的分析方法。确立了前处理方法、高效液相色谱仪色谱分离条件和质谱检测条件。该方法前处理采用超声提取后高速离心净化,具有操作过程简便、耗时短、有机溶剂用量少、线性和重复性良好等特点。通过对实际样品的测定,表明该方法具有较好的实用性。可为水性涂料产品中有害物质检测提供简便可行的检测方法。A method for the rapid determination of alkylphenol polyoxyethylene(octylphenol polyoxyethylene ether and nonylphenol polyoxyethylene ether(n=2~16)) in waterborne coatings. The pretreatment method, high performance liquid chromatography(HPLC) separation conditions and mass spectrometry detection conditions were established. After ultrasonic extraction and high-speed centrifugal purification, the method is simple, quick, less using of organic solvent, good linearity and repeatability. Through the determination of actual samples, it is proved that this method has good practicability. It provides a simple and feasible method for the detection of harmful substances in waterborne coatings.
