Abstract
The laboratory generated spent bleach liquor from the chlorination and caustic extraction stages of bagasse and wheat straw pulps have been analysed both qualitatively and quantitatively for various chlorophenolics, resin and fatty acids using gas chromatography. A number of chlorinated derivatives of phenols, catechols, guaiacols. syringaldehydes, resin acids as well as unchlorinated saturated and unsaturated fatty and resin acids have been identified. The concentrations of various compounds identified have also been compared with the reported 96LC50 values.
