In this article, quantitative determination of compositions (hemicellulose and lignin) in the APMP (alkaline peroxide mechanical pulping) effluent was done. The MTBE (methyl tert-butyl ether) extracts of the APMP effluent (extractives) were analyzed by GC/MS (gas chromatography-mass spectrometry). The result of GC/MS showed that fatty acids (C14-C28) and their esters, sterols were the main ...
