摘要

Method for the determination of thiophanate methyl pesticide using electrochemical electrode type abnt 304 stainless steel with the surface modified with gold nanoparticles.The process of determining electrochemistry of the pesticide methyl thiophanate (TM) using abnt 304 type stainless steel electrode modified with gold nanoparticles, this process is carried out in Britton Robinson buffer solution of 0.1 mol L - 1, containing aliquots of the pesticide tiofanat The methyl (TM) in a range from 5 to 50x10 - 6 mol L - 1.The referring process leads to greater efficiency in the quantification of pesticide residues for application in various complex matrices. The use of an ultra fast technical organization of molecules of gold on the metal surface, coupled with the low cost of the electrodes used, allows the use of this elet squeegee modified for determination of pesticides, efficiently and quickly.
