Isolation and identification of toxic chlorinated organic compounds present in black liquor of bleached cellulose pulp from Southern Brazil
Chemical components of untreated black liquor of cellulose pulp from Southern Brazil were extracted using macromolecular XAD-4 resin. The following compounds were identified qualitatively and/or quantitatively by capillary gas chromatography: phenol; guaiacol; catechol; 3,4-dichlorocatechol; 3,4,5-t...

| Sumario: | Chemical components of untreated black liquor of cellulose pulp from Southern Brazil were extracted using macromolecular XAD-4 resin. The following compounds were identified qualitatively and/or quantitatively by capillary gas chromatography: phenol; guaiacol; catechol; 3,4-dichlorocatechol; 3,4,5-trichloroguaiacol; 4,5,6-trichloroguaiacol; 3,4,5-trichloroguaiacol; pentachlorophenol; tetrachloroguaiacol; triachlorosyringol and tetrachlorocatechol. The retention indexes of some of these toxic mutagenic compounds were also determined. |
