Description
Summary:<abstract language="eng">The objective of this study was to evaluate the use of the matrix solid-phase dispersion technique associated with purification at low temperature for the determination of pyrethroids in butter. Evaluated parameters included: sample/adsorbent ratio, type of adsorbent and extractor solvent. The optimized method was validated based on predetermined requirements. The detection limits of the pyrethroids cypermethrin and deltamethrin were 0.082 and 0.11 &#956;g g-1, and quantification limit were 0.28 and 0.32 &#956;g g-1, respectively, with extraction percentages near 90% and coefficients of variation less than of 10%..
