Abstract
In this study, soxhlet extraction and dissolution-precipitation method are used for separating analytefrom polymer materials. In soxhlet extraction efficiency test, it has been found that the DCM, Toluene, THF,and mixtures Acetone/Hexane (1:4, v/v) gave good extraction efficiency, while the use of the ethyl ether, acetone/ethyl ether (1:4, v/v), acetone/hexane (1:1, v/v), DCM/hexane (1:1, v/v) resulted in significantly lower values.In case of dissolution-precipitation method, there is no considerable diference with used different dissolvingsolvent. The elution amount of multi layer silica and Florisil column were determined with hexane 250 mLand 70 mL of hexane, respectively. Range of PBDE in real waste plastics was N.D.~1.028 ppm.
