Abstract
A new method for determination of polychlorinated dibenzo-p-dioxins, polychlorinated dibenzofurans, and dioxin-like polychlorinated biphenyls in fats based on the use of Carboxen 1000 and 1016 sorbents has been proposed. The use of Carboxen 1000 obviates the stage of chemical degradation of the fat matrix, thus providing high quality of the extract purification at shorter sample preparation times and a relatively small solvent consumption. The recovery values were slightly lower than in common methods of sample preparation but, nonetheless, conformed to the criteria of Russian and foreign standard methods. The method can be used to analyze animal fats and vegetable oils from food and animal feeds.
