The present work
describes the validation of an analytical method for chromatographic
determination of chlorimuron ethyl herbicide (compound of sulphonylurea group)
in sediments, in according with Brazilian legislation, following the guidance
and normative documents of INMETRO (DOQ-CGCRE-008) and ANVISA (Resolution RE no
899 - 2003). The results show that the chromatographic method demonstrated to
be selective, accurate, precision and linear over the concentration range of
5.0-1000.0 ug L-1. Besides, limits of quantitation and determination
were satisfactory, 29.48 and 8.84 ug L-1, both determined by
calibration curve. The method proposed also showed good results for assays of
recovery, with confidence intervals between 80 and 100%, approximately, with
accuracy and precision.
