摘要
Two vibrational spectrometry-based methodologies were developed for procymidone determination in wettable powdered pesticide formulations. The Fourier-transform infrared (FTIR) procedure was based on the selective extraction of procymidone by chloroform and determination by peak area measurement between 1451 and 1441 cm(-1), using a baseline correction established between 1490 and 1410 cm(-1), and a precision of 0.4% and a limit of detection of 0.01% w/w procymidone for a sample mass of 25 mg were obtained. For FT-Raman determination, the selected conditions were peak area measurement between 1005 and 995 cm(-1) Raman shift, with a baseline correction fixed between 1030 and 947 cm(-1), and a relative standard deviation of 1% and a limit of detection of 0.8% procymidone in the original sample were obtained. The sample frequency for FTIR determination was 30 hr(-1), lower than that for Raman with 40 hr(-1). FT-Raman reduces to the minimum the reagent consumption and waste generation, also avoiding the sample handling and contact of the operator with the pesticide. It can be concluded that the proposed methods are appropriate for quality control in commercial pesticide formulations.
