Simultaneous Determination of Nonylphenol and Short-Chain Nonylphenol Polyeothoxylates by Gas Chromatography Coupled to Mass Spectrometry
This paper presents a method for the simultaneous determinat of NP and NPEO1-2 using GC-MS in sludge samples. using ultrasonic extraction, derivatization techniques, the results show that good separation of three substances, a well-shaped peak can be observed on every selected ion chromatogram. the ultrasonic extraction recoveries ranged from 80% to 102% , the instrumental limits of detection for these compounds were 2 ng/g、2 ng/g and 1.5 ng/g and the relative standard deviation(RSD) was below 15%. The establishment of this method provided the method safeguard for the control of NP and NPEO1-2 in sludge samples.
