Title: Determination of Trace Organochlorine Pesticide in Water by Solid Phase Extraction and GC-MS
Abstract: The C18 solid-phase extraction(SPE) pre-treatment,GC-MS and selective ion monitoring(SIM) mode were used to determine five kinds of organochlorine pesticides(OCPs) in water.The orthogonal test of the main factors influencing SPE was carried out,and the optimal extraction conditions were obtained,in which dichloromethane was eluting solvent,eluting rate was 0.5 mL/min,eluting solvent volume was 3 mL,and flow rate of water sample was 10 mL/min.The linear range,linear relativity and minimum detection limits of five OCPs were also determined.The results show that the method has better linear relativity,high precision and good accuracy.It is suitable to determine the trace OCPs concentration in water.
