There is a significant need to characterize and classify lignins and sulfonated lignins. Lignins have so far received a good deal of attention, whereas this is not true for sulfonated lignins. There is a clear demand for a better understanding of sulfonated lignins on a chemical as well as physical level. Many of the analytical methods have been developed with different goals in mind, for example, detection of sulfonated lignins in pulp-mill effluents, elucidation of structural changes in lignosulfonates during a pulping process, or identification of properties that may affect a formulation when sulfonated lignins are used as a dispersant. When sulfonated lignins are used in industrial applications, analytical data obtained using different techniques may be necessary to enable prediction of their behavior in the target application. In the present review, a critical discussion of established and promising analytical techniques for the characterization of sulfonated lignins is presented.
需要对木质素和磺化木质素进行特征描述和分类。迄今为止，木质素受到了相当多的关注，而磺化木质素则不然。人们显然需要更好地了解磺化木质素在化学和物理层面上的情况。许多分析方法是为了不同的目的而开发的，例如，检测纸浆厂废水中的磺化木质素，阐明磺化木素在制浆过程中的结构变化，或者在磺化木质素用作分散剂时，确定可能影响配方的性能。当磺化木质素在工业应用中使用时，可能需要使用不同技术获得的分析数据来预测它们在目标应用中的行为。在本综述中，对用于磺化木质素特性描述的既定和有前途的分析技术进行了批判性讨论。
