Method for measuring 34 plasticizers in four types

The invention discloses a method for measuring 34 plasticizers in four types. The method adopts the ultrasonic extraction technique and takes ethyl acetate as an extracting solvent, 34 plasticizers infour types like phthalate ester, adipate, phosphate and acetyl citrate in a plastic product are extracted, the extracting method is simple, and an extracting solution is measured by gas chromatography-mass spectrometry. The provided detecting method can measure four types of plasticizers at the same time, and is wide in coverage, strong in applicability, high in sensitivity, simple, fast, and successfully applied to the practical detection of the plasticizers in the plastic product. 本发明公开了种塑料制品中四类34种增塑剂的测定方法。该方法采用超声萃取技术，以乙酸乙酯为萃取溶剂，萃取塑料制品中邻苯二甲酸酯类、己二酸酯类、磷酸酯类、乙酰柠檬酸酯类四类34种增塑剂，萃取方式简单；萃取液经气相色谱-质谱法测定。本发明提供的检测方法可以同时测定四类增塑剂，涵盖面广，适用性强，方法灵敏度高、简单快速，并成功应用于实际塑料制品中增塑剂的检测。
