DETERMINATION OF CHLORINE AND PENTACHLOROPHENOL IN WOOD

Chlorine in wood was determined in connection with the development of a reference material (RM) of pentachlorophenol (PCP) in wood. The elem ent was determined by photon activation analysis (PAA) using bremsstra hlung of 19 MeV electrons from an electron linear accelerator. The ini tial overall Cl content as well as the Cl remaining after extraction w ith methanol and subsequent extraction with water were determined. Mor eover, the PCP fractions in the organic and in the aqueous extracts we re analyzed by gas chromatography (GC). The results show that at least three quarters of the overall chlorine is bound in PCP and that PCP c an be extracted to a high degree.
