目前，木质素主要在制浆过程中产生，但由于其主要用作燃料来源，因此被认为是未充分利用的化学品。木质素含有许多羟基，可以参与化学反应产生增值产品。絮凝剂、吸附剂和分散剂在工业上有着广泛的应用，但它们主要是油基化学品，价格昂贵。本文综述了水溶性木质素絮凝剂、吸附剂和分散剂的制备方法。它提供了这些木质素为基础的絮凝剂，吸附剂和分散剂的可能使用的最新进展的信息。它还批判性地讨论了生产这种产品的各种方法的优点和缺点。木质素为基础的絮凝剂，吸附剂和分散剂的生产和可能的情况下，以克服这些挑战，这些产品在工业中的商业用途的挑战进行了讨论。
Currently, lignin is mainly produced in pulping processes, but it is considered as an under-utilized chemical since it is being mainly used as a fuel source. Lignin contains many hydroxyl groups that can participate in chemical reactions to produce value-added products. Flocculants, adsorbents, and dispersants have a wide range of applications in industry, but they are mainly oil-based chemicals and expensive. This paper reviews the pathways to produce water soluble lignin-based flocculants, adsorbents, and dispersants. It provides information on the recent progress in the possible use of these lignin-based flocculants, adsorbents, and dispersants. It also critically discusses the advantages and disadvantages of various approaches to produce such products. The challenges present in the production of lignin-based flocculants, adsorbents, and dispersants and possible scenarios to overcome these challenges for commercial use of these products in industry are discussed.
