So the paper is mainly study the rapid detection of pesticide with electrochemical and solid phase extraction techniques.A Single-sweep polarography was described for the determination of trace dichlorvos with sodium perborate and benzidine. The detection limit and the linear range were 1.0ug /mL and 3.0ug/L~7.5mg/mL (R2=0.9992) respectively.

On the basis of the analytical results of infrared spectrometry,paper chromatography,tyrosine color development reaction and the assay of anti-acid buffer capability,we confirm that chlorine dioxide in stabilized solution with sodium percarbonate as stabilizer exists in the form of chlorition (ClO2-) and exists in NaHCO3-Na2CO3 buffer system. When the stabilizer is sodium perborate,chlorine dioxide may be retained in the solution comprised of H3BO3-Na2B4O7 as a labile complex.
