摘要
亚硫酸氢镁法荻苇浆制浆废液经超滤提取木质素磺酸盐后，超滤滤过液经三氯甲烷萃取，并将可萃取有机物分为酸性和中性二个组份，采用GC－MS技术对二个组份进行了定性分析。酸性组份中检测到的主要成分为脂肪酸和低分子木质素降解产物。
After the Lignosulfonate of MgSSL was separated by ultrafiltration, the fil-trate was extracted by CHCls, and the extractable organic compounds were devided intoacidic and neutral fractions by a series of sampling procedure. GC-MS Spectra were usedto analyze the organic compounds in the acidic and neutral fractions. Major componentsof acidic fraction determined by GC-MS were fatty acids and low molecular resultingcompouds from lignin degradations during pulping process.
