原始语种摘要: A simple, sensitive, and reliable procedure based on stir bar sorptive extraction coupled with high‐performance liquid chromatography was applied to simultaneously extract and determine three semipolar nitrosamines including N ‐nitrosodibutylamine, N ‐nitrosodiphenylamine, and N ‐nitrosodicyclohexylamine. To achieve the optimum conditions, the effective parameters on the extraction efficiency including desorption solvent and time, ionic strength of sample, extraction time, and sample volume were systematically investigated. The optimized extraction procedure was carried out by stir bars coated with polydimethylsiloxane. Under optimum extraction conditions, the performance of the proposed method was studied. The linear dynamic range was obtained in the range of 0.95–1000 ng/mL ( r =...
