C. Sharma et al., GAS-CHROMATOGRAPHIC ANALYSIS OF CHLOROPHENOLIC, RESIN AND FATTY-ACIDSIN EFFLUENTS FROM BLEACHING PROCESSES OF AGRICULTURAL RESIDUES, International journal of environmental analytical chemistry, 64(4), 1996, pp. 289-300
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 chloropheno
lics, resin and fatty acids using gas chromatography. A number of chlo
rinated 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 co
mpounds identified have also been compared with the reported (96)LC(50
) values.
