J. Nowak et L. Lewandowska, DETERMINATION OF ATRAZINE AND PROMETRYNE RESIDUES IN THE SOIL BY GAS-CHROMATOGRAPHY, Chemia Analityczna, 42(2), 1997, pp. 239-243
A method for combined assay of atrazine and prometryne residues in soi
l was worked out. The extraction was performed by shaking with chlorof
orm. Dehydrated, cleaned and thickened extracts were analysed by gas c
hromatography using Carlo Erba-Vega 6180 chromatograph. The average re
covery of atrazine from soil was 91.5+/-4.2%, and prometryne 92.0+/-3.
2% The least detectable amount of the herbicides in soil was 0.005 mg
kg(-1).
