Gas chromatographic analysis of chlorophenolic, resin and fatty acids in chlorination and caustic extraction stage effluent from Kahi-grass
Abstract
Laboratory generated spent bleach liquor from the chlorination and caustic extraction stages of Kahi-grass pulp processing has been analysed both qualitatively and quantitatively for various chlorophenolics, resin and fatty acids using GC. A number of chlorinated derivatives of phenols, catechols, guaiacols, syringaldehydes and resin acids as well as unchlorinated saturated, unsaturated fatty and resin acids have been detected. The concentration of various compounds detected have been compared with the reported 96LC50 values.
