To overcome the technical bottleneck of fine amyloid lysozyme fibrils in environmental engineering, a novel co-operative strategy was identified to fabricate free-standing lysozyme complex nanofibers based membrane-type adsorbent (Lys-CNFs membrane) through a combination of vacuum filtration for lead remediation. The composition of the membrane integrated the linear amyloid protofilaments that were obtained by acid-heating fibrillation and polydopamine that adjusted the fibers’ diameters and surface chemistry. As expected, the Lys-CNFs membrane not only showed nanofibrous morphology and layer stacking architecture but presented a hierarchical macro-mesoporous structure along with a high surface area of 220.4 m²/g. Besides, the thermal stability up to 200 ℃ and wetting nature of below 2 s endowed its further applicability. Adsorption experiments showed that Lys-CNFs membrane can effectively uptake Pb(II) ions with acceptable selectivity, high adsorption capacity of 270.3 mg/g, rapid equilibrium kinetic within only 10 mins, and good reusability that dropped by 14.9% efficiency even after five cycles, indicating that Lys-CNFs membrane can be as an affordable technology for alleviating the lead pollution issues.

为克服精细淀粉样溶菌酶原纤维在环境工程中的技术瓶颈，确定了一种新的合作策略，通过真空过滤组合制备自支撑溶菌酶复合纳米纤维膜型吸附剂（Lys-CNFs 膜）用于铅修复. 膜的成分整合了通过酸加热原纤化获得的线性淀粉样蛋白原丝和调节纤维直径和表面化学的聚多巴胺。^{正如预期的那样，Lys-CNFs 膜不仅表现出纳米纤维形态和层堆叠结构，而且呈现出分层的大介孔结构以及 220.4 m 2}的高表面积。/G。此外，高达200 ℃的热稳定性和低于2 s的润湿性赋予了其进一步的适用性。吸附实验表明，Lys-CNFs 膜可以有效吸收 Pb(II) 离子，选择性可接受，吸附量高达 270.3 mg/g，10 分钟内达到快速平衡动力学，重复使用性好，即使经过 5 次循环，效率也下降了 14.9% ，表明Lys-CNFs膜可以作为一种经济实惠的技术来缓解铅污染问题。
