J. Mao et al., SIMULTANEOUS DETERMINATION OF TRALOMETHRIN, DELTAMETHRIN, AND RELATED-COMPOUNDS BY HPLC WITH RADIOMETRIC DETECTION, Journal of agricultural and food chemistry, 41(4), 1993, pp. 596-601
Analytical methodologies for the simultaneous determination of the syn
thetic pyrethroids tralomethrin, deltamethrin, and decamethrinic acid
(Br2CA) in water, sediment, and fish tissue by HPLC with radiometric d
etection (HPLC-RAM) are described. The separation of the three compoun
ds was achieved using a hexane/dioxane gradient solvent system on a si
lica column. This solvent system could also be used to resolve alpha-(
R)-deltamethrin from trans-deltamethrin. Water, sediment, and fish tis
sue sample preparation involved relatively simple solvent extractions.
The quantitation of these pyrethroids was validated at low nanograms
per liter (parts per trillion) concentrations for water samples and lo
w nanograms per gram (parts per billion) levels for sediment samples.
The objective of this work was to provide a relatively simple, rapid,
and sensitive method which permits the simultaneous identification and
quantification of radiolabeled tralomethrin, deltamethrin, and their
related compounds.
