Abstract: The status of the pesticide residue in citrus fruits was introduced briefly.Most of novel pre- treatment techniques and detection techniques were analyzed in the paper.The pre-treatment methods included to the solid-phase microextraction, matrix solid- phase dispersion, molecular imprinted solid- phase extraction, multi- walled carbon nanotubes solid-phase extraction, hollow fiber liquid-phase microextraction, chromatography dual counter-current chromatography, QuEChERS and so on.The detection techniques included to kinds of chromatography, non- destruction test technology which based on spectroscopy and biosensors.The research emphasis and direction on pesticide in China were analyzed and suggested.
