建立了固相萃取联合超高效液相色谱质谱 (UPLC-QTOF-MS) 联用技术鉴定水性胶黏剂及乳液原料中的表面活性剂结构鉴定的方法。聚合物乳液样品经过稀释以及离心处理，然后采用固相萃取技术获取表面活性剂纯化浓缩液，固相萃取的条件及萃取效率得到了优化，最终选用了聚苯乙烯 / 二乙烯苯高聚物填料的 SPE 柱，建立了一般乳液中表面活性剂的固相萃取流程，获得的萃取液经过 UPLC-QTOF-MS 测定获得表面活性剂的质谱信息来解析表面活性剂种类，并与标准物质的质谱信息比对最终确认表面活性剂的结构。“,”Solid phase extraction combined UPLC-QTOF-MS method was successfully developed to detect the chemical structure of surfactants in water-based polymer emulsions, especially water-based adhesives and its polymer emulsions. The water based polymer emulsion was firstly diluted with LCMS water and the polymer precipitation was removed with centrifugation. Then the water solution was processed with SPE technique. The SPE column type was optimized and finally polystyrene/Divinylbenzene adsorbent was selected. And the procedure for surfactants concentration and purification from water based polymer emulsions was created, then the solution sample was tested with UPLC-QTOF-MS, and thus the surfactant chemical structure was determined, also surfactant standards were compared to make a verification.
