Liquid Chromatographic Determination of Sulfentrazone in Soil

Abstract

A rapid method for the determination of sulfentrazone in soils is described. The method consists of extraction of soil samples with methanol, filtration, liquid chromatographic separation of methanol-soluble components through a C18 column, and ultraviolet detection at 220 nm. Recoveries from fortified surface soils were >85% for sulfentrazone. Average relative standard deviations over the soils examined was 7.7%. A conservative lower limit of quantitation for sulfentrazone was 40 ng/g soil.

“…A conservative lower limit of detection was 40 ng/g. A complete description of analytical methods has been previously published (Ohmes and Mueller 1999).…”

Sulfentrazone Dissipation in a Tennessee Soil1

“…A nontreated control plot was included in the field experiment design. Soil samples from plots that received 840 g/ha of sulfentrazone were evaluated using chemical extraction followed by liquid chromatography (Ohmes and Mueller 1999). Soil from the 840 g/ha plots was analyzed to ensure analytical detection and because herbicide dissipation is usually independent of application rate (Hurle and Walker 1980).…”

“…The sulfentrazone quantification was performed according to a method proposed by Ohmes et al (1999) [ 21 ] and adapted by Passos et al (2013) [ 22 ], utilizing a photodiode array detector (Shimadzu SPD-M20A) and a C18 stainless steel column (Shimadzu VP-ODS Shim-pack 250 mm × 4, 6 mm id, 5 μm particle size).…”
