Resumo(s)
A multiresidue approach using microwave-assisted extraction and liquid
chromatography with photodiode array detection was investigated for the determination
of butylate, carbaryl, carbofuran, chlorpropham, ethiofencarb, linuron,metobromuron,
and monolinuron in soils. The critical parameters of the developed
methodology were studied. Method validation was performed by analyzing freshly
and aged spiked soil samples. The recoveries and relative standard deviations reached
using the optimized conditions were between 77.0 ± 0.46% and 120 ± 2.9% except
for ethiofencarb (46.4 ± 4.4% to 105 ± 1.6%) and butylate (22.1 ± 7.6% to
49.2 ± 11%). Soil samples from five locations of Portugal were analysed.
