摘　　要：对黑液的成分进行分析。利用改进酸析法分级分离析出黑液中的木素,并用紫外法对酸析后黑液中的木素进行定量分析。实验结果表明,酸析木素占黑液中总木素的比例可达90%以上,证明应用此法分离黑液中的木素是可行的。The composition of black liquor was analyzed, then dissolved lignin was separated by fractionation with acidulation precipitation, and the UV lignin was quantified by UV analysis. The result showed that UV lignin is more than 90% of the total lignin in the black liquor. In other words, using acidulation precipitation can separate lignin from the black liquor is completely feasible.
