Abstract Electrospinning technology can produce nanofibers with extremely high specific surface area. Bio‐based polyamide 56 (PA56) was combined chitosan (CS) to prepare PA56/CS composite nanofibers. An in vitro mineralization experiment conducted obtain a super hydrophilic fiber (PA56/CS‐HAP) hydroxyapatite deposited on the surface. The adsorption performance of evaluated by adsorbent dosage, solution pH value, and kinetics. curves obtained after fitting kinetics isotherms show that behavior under = 6 is more consistent Langmuir model. capacity 100 mg L −1 Pb 2+ environment than 5 times 10 . static‐spun nanocomposite fibers prepared have great potential environmental protection, sensors, chemical engineering, other fields. Highlights PA/CS were electrospinning. Hydroxyapatite technique. PA/CS‐HAP achieves effect. Pb(II) reached 27.5 g After fitting, process adsorption.
