GC-NCI-MS法测定塑胶跑道中的中链氯化石蜡
Determination of Medium Chain Chlorinated Paraffins in Plastic Track by GC-NCI-MS
摘要
Abstract
A gas chromatography negative chemical ionization source mass spectrometry(GC-NCI-MS)was established to determine the content of medium-chain chlorinated paraffins(MCCPs)in plastic tracks.This method uses n-hexane as the solvent to ultrasonically extract MCCPs from plastic track samples,after purification with sulfuric acid,the 24 isomers of MCCPs were determined using external standard method for quantification.The experimental results show that the linear correlation coefficient of MCCPs is greater than 0.995 in the concentration range of 10 mg/L to 50 mg/L,and the method detection limit is 57.0 mg/kg.The recovery range of the high,medium,and low levels of spiked samples is 88.4％to 100.6％,and the relative standard deviation range is 3.03％to 3.95％.This method can meet the detection requirements of MCCPs in plastic track samples.关键词
