In
this study, the efficiency of a clean-up method by gel permeation chromatography
(GPC) for the separation of pesticides from lanolin is analyzed. The pesticides
analyzed belong to two different families, organophosphorous and synthetic pyrethroids.
Lanolin, a standard mixture of the pesticides, and a lanolin–pesticides
mixture are injected in a GPC column. The recoveries and elution times from
the GPC column of lanolin (by a gravimetric method) and pesticides (by gas chromatography–electron
capture detector) are determined. From this column, a good separation of the
lanolin–pesticides mixture is observed.
