Abstract:
In this paper a new extraction method has been established for extraction of two antioxidants, Irganox 1010 and Irgafos 168 Simultaneous from low density polyethylens. Carbon tetrachloride were used as extraction solvents that extract additives in 125˚C, The extracts were analyzed by HPLC , and acetonitrile were used as mobile phase at a wavelength of 230 nm. Effects of temperature, time, weight of polymer and volume of solvent on the extraction efficiency were studied. It is simple, rapid, and efficient; with high recovery.The performed method allows extracting at high temperature in a short time without degradation of studied antioxidants.
