Using GC to determinate polychlorinated biphenyls in soil after pretreated with microwave-assisted alkaline degradation method
摘要
Abstract
A new and simple microwave-assisted alkaline degradation (MAAD) method for the elimination of organochlorine-pesticide interference on the determination of polychlorinated biphenyls (PCBs) in soil by GC is presented. Under the optimal conditions, the interference of α-HCH, β-HCH, γ-HCH, δ-HCH, o. p'-DDT, p. p'-DDD and p. p'-DDT could be eliminated completely, and p. p'-DDE, Aldrin and Dieldrin could be partially eliminated; however, Dieldrin could be completely eliminated by using concentrated sulphuric acid. The method was evaluated by analyzing the spiked-soil sample. The mean recovery obtained was 84. 1%and the Relative Standard Deviation (RSD) was 2.7%. Experimental results also indicate that the degradation of the interference and the extraction of the target analytes, PCBs, could be carried out simultaneously. Compared with the traditional methods, the MAAD method is a rapid, efficient and solvent-saving method.关键词
