    Determination of Organochlorine Pesticides in Carex Cinerascens of Poyang Lake Wetland by GC

    • Received Date: March 20, 2014
    • GC was applied for the determination of 8 kinds of organochlorine pesticides in carex cinerascens of Poyang Lake wetland. The sample of carex cinerascens was collected, dried, and then extracted with acetone-petroleum ether (1+1) by ultrasonic. The extract was concentrated to near dryness and the residues were dissolved with methanol. The target analytes were separated on an Agilent 19091-413 column and detected by ECD. The linear relationship between the peak area and the mass concentration of the 8 kinds of organochlorine pesticides was in the range of 2.00-100.0 μg·L-1, with detection limits (3S/N) in the range of 0.6-1.3 μg·L-1. The recovery rate measured by standard addition method was in the range of 80.4%-114%, with RSD (n=6) in the range of 1.1%-5.9%.
