A combined QuEChERS extraction/preconcentration methodology for the precise determination of pesticides in wastewater and sludge matrices.
In this study, an analytical methodology for the determination of pesticides commonly found in sludge and wastewater was developed and validated based on the citrate-buffered QuEChERS (Quick, Easy, Cheap, Effective, Rugged, Safe) extraction procedure. More specifically, to achieve a limit of quantification of 0.001 mg/...
