Five-way ANOVA Interaction Analysis of the Selective Extraction of Carbaryl, Pirimicarb and Aldicarb From Soils by Supercritical Fluid Extraction

Supercritical Fluid Chromatography and Extraction

“…Lopez-Avila et al converted chlorophenoxy acid herbicides to their pentafluorobenzyl bromide esters prior to using CO 2 to extract these compounds from soil (328). Two papers reported the SFE extraction of carbamate pesticides from soils (329,330). Other pesticide-related SFE applications included the extraction of naled, methyleugenol, and cuelure in soils (331), azadirachtin in soils and insects (332), cyanazine herbicides in soils (333), metribuzin in soil (334), acifluorfen in organic soils (335), chlorsulfuron and tribenuronmethyl in soil (336), and nitrogen-or phosphorus-containing pesticides in wet soils (337).…”

Supercritical fluid extraction (SFE) as a multi-residue extraction procedure for β-agonists in bovine liver tissue

“…Supercritical fluid extraction (SFE) is finding wide acceptance in a number of analytical disciplines as a unique extraction technique due to inherent properties such as the avoidance of large quantities of organic solvents, speed of extraction and the capability to manipulate solvent strength. Supercritical carbon dioxide (SF-CO 2 ) is the most widely used supercritical solvent, and in the area of residue analysis has been successfully applied to the extraction of relatively non-polar analytes, such as pesticides, 1,2 herbicides, 3 and fungicides 4 from a range of matrices. However, the most important limitation of SF-CO 2 is that its polarity is often too low to obtain efficient extraction, either because the analytes lack sufficient solubility or because the extractant has a poor ability to displace the analytes from active matrix sites.…”
