摘要：

Three mono-chlorinated compounds derived essentially from glucuronoxylan were identified as the major components of the ethyl acetate extract from chlorine dioxide bleaching filtrates of E. globulus kraft pulp; one of them is reported for the first time. It was demonstrated that these components are responsible for an important fraction of the total AOX of the filtrates. The ecological risk associated with these compounds is expected to be negligible since they are easily degraded and not detected in the final mill effluent.
