摘要：

In this paper, lignin-based nanofiber materials with excellent adsorption performance were prepared by electrospinning technology with waste lignin as raw material and doped Ni-MOF-74. Through a series of characterization of the adsorbent, the effects of fiber morphology, pore size distribution, and doping Ni-MOF-74 on chlorobenzene adsorption performance were studied. It showed that doping Ni-MOF-74 could effectively increase the specific surface area of the adsorbent, enrich the pore structure, which was conductive to the adsorption. The results showed that Ni-MOF-74 doped lignin fiber exhibits excellent chlorobenzene adsorption performance compared with Ni-MOF-74 material and lignin fiber, and the maximum adsorption capacity can reach 58.49 g/g. According to the calculation of Langmuir equation, the chemical adsorption plays a leading role in the adsorption process of chlorobenzene.
