Análise de pesticidas organoclorados em óleos vegetais por cromatografia gasosa de alta resolução (HRGC)

Abstract: Vegetable oil were introduced in human diet in the last decade to change the use of animal fats. The chemical products althrought utilized in correct manner can cause residues in food bring to healt there be a necessity of a constant monitoring of the concentration level the several agricultural products. The answer to this necessity has motivated the development of several of a methodology for simultaneous analysis of aldrin, dieldrin, endrin and endosulfan in vegetable oils by HRGC, using solid phase extraction (SPE) using silica and XAD-2. The recovery was 70-110% Keywords: analysis, pesticide, oil, chromatography, extraction Referencias [1] H.W.Lawson. Standards Fo fats & Oil. 2ed Wesport, (1985) 30.[2] A. S. Y CHAU. B. K AFGHAM.
