木质素是木材制浆工业的副产品，主要作为非商业化的废物处理。因此，研究其将这种可再生和可持续资源转化为高价值化学品和材料的潜力具有重要意义。在这项研究中，一个可再生的木质素基材料具有良好的性能和环境友好的废水处理性能已被探索。本文以四氢呋喃-Fe 3 O 4纳米粒子混合水溶液为介质，采用马来酸酐（MA）酯化木质素，通过自组装的方法制备了木质素空心微球（LHM）。此外，磁性木质素球（MLS）也成功地通过引入Fe 3 O 4纳米粒子。采用TEM、SEM、VSM和FT-IR等手段对酯化木质素聚合物的结构变化进行了表征，并对酯化木质素聚合物的形态和性能进行了表征，同时还研究了酯化木质素聚合物对亚甲基蓝和亚甲基蓝的吸附性能。
Lignin, a byproduct of the wood-pulping industry, is mostly treated as a noncommercialized waste product. Therefore, it is significant to study its potential for the conversion of this renewable and sustainable resource into high-valued chemicals and materials. In this study, a renewable lignin-based material with high performance in wastewater treatment has been explored on account of its satisfactory properties and being environmentally friendly. Herein, lignin hollow microspheres (LHM) were facilely prepared from esterified organosolv lignin with maleic anhydride (MA) via self-assembly in the mixed tetrahydrofuran–Fe3O4 nanoparticles aqueous media. Moreover, the magnetic lignin spheres (MLS) were also successfully fabricated by introducing Fe3O4 nanoparticles. The structural changes of esterified lignin polymers were identified and morphology and property of obtained LHM and MLS were characterized by means of TEM, SEM, VSM and FT-IR. In addition, the adsorption capacities of MLS for methylene blue and ...
