摘要
拟除虫菊酯农残检测前处理技术是制约其分析速度和分析准确度的瓶颈。综述最近几年应用于拟除虫菊酯类农药残留检测前处理技术如萃取技术(包括超临界流体萃取、加速溶剂萃取、超声波萃取、微波辅助萃取和液相微萃取等)、净化技术(包括凝胶渗透色谱和固相萃取等)以及基于固相微萃取和基质固相分散萃取等萃取、净化一体化技术的国内外研究进展,为我国更好的开展农残检测工作提供理论依据与技术支撑,并对其发展趋势进行了展望。
Sample pretreatment techniques in the detection of pyrethroid residues have been the bottleneck of restricting its analysis speed and accuracy. The recent progresses on the studies of pretreatment techniques in the detection of pyrethroid residues were reviewed. The methods described consist of extraction techniques which include supereritical fluid extraction, accelerated solvent extraction, ultrasonic extraction, microwave-assisted extraction and liquid-phase micro-extraction; purification techniques which include gel permeation chromatography and solid-phase extraction, and integration techniques based on solid-phase micro-extraction and matrix solid-phase dispersion extraction. A theoretical basis and technical support were provided for our country to carry out better testing of pesticide. Their development prospects were also discussed in the end.
