ABSTRACT:
A process for the extraction and purification of TCDD (2,3,7,8-Tetrachlorodibenzo-p-dioxin) from a sample matrix. The process of the present invention overcomes a problem of prior art processes for extracting TCDD, by providing for chemical destruction of potentially interfering components in a sample matrix making the steam distillation of TCDD possible. A typical sample matrix comprises blood serum.
