Electrospun chitosan/poly(ethylene oxide) nanofibers were synthetized, characterized and applied as alternative biosorbents to remove pigments from pretreated crude glycerol. The pigments removal efficiency of electrospun nanofibers was examined by comparing the adsorption capacity of nanofibers with other chitosan–based biosorbents. Pseudo–first order, pseudo–second order and Elovich models were used to estimate kinetic parameters. The nanofibers exhibited continuous fibers, with the average fibers diameter of 526 ± 101 nm. The results also indicated interactions between chitosan and poly(ethylene oxide) molecules, without changing the main adsorptive sites of chitosan. Furthermore, chitosan/poly(ethylene oxide) nanofibers exhibited higher relative adsorption capacity (120 g⁻¹) than chitosan powder (35 g⁻¹) and chitosan biopolymeric film (58 g⁻¹). The pseudo–first order and Elovich models were the most suitable models to represent the kinetic behavior of the composite nanofiber.

合成了静电纺丝的壳聚糖/聚环氧乙烷纳米纤维，对其进行了表征，并将其用作替代性生物吸附剂，以从预处理的粗制甘油中去除色素。通过比较纳米纤维与其他基于壳聚糖的生物吸附剂的吸附能力，检查了电纺纳米纤维的色素去除效率。伪一阶，伪二阶和Elovich模型用于估计动力学参数。纳米纤维表现出连续的纤维，平均纤维直径为526±101nm。结果还表明壳聚糖和聚环氧乙烷分子之间的相互作用，而没有改变壳聚糖的主要吸附位。此外，壳聚糖/聚环氧乙烷纳米纤维比壳聚糖粉（35 g）具有更高的相对吸附容量（120 g ^-1）。^-1）和壳聚糖生物聚合物薄膜（58 g ^-1）。伪一阶模型和Elovich模型是最合适的代表复合纳米纤维动力学行为的模型。
