Preparation of bio-based polyamide 56/chitosan heavy metal adsorbing nanocomposite fibers by electrospinning
Electrospinning technology can produce nanofibers with extremely high specific surface area. Bio-based polyamide 56 (PA56) was combined with chitosan (CS) to prepare PA56/CS composite nanofibers. An in vitro mineralization experiment was conducted to obtain a super hydrophilic composite fiber (PA56/CS-HAP) with hydroxyapatite deposited on the surface. The adsorption performance of the composite fiber (PA56/CS-HAP) was evaluated by the adsorbent dosage, solution pH value, and adsorption kinetics. The curves obtained after fitting the kinetics and adsorption isotherms show that the adsorption behavior under pH = 6 is more consistent with the Langmuir adsorption model. The adsorption capacity in a 100 mg L−1 Pb2+ environment is more than 5 times that of 10 mg L−1. Bio-based PA56/CS static-spun nanocomposite fibers prepared by in vitro mineralization have great potential in environmental protection, sensors, chemical engineering, and other fields.
Highlights
PA/CS fibers were prepared by electrospinning.
Hydroxyapatite was deposited by in vitro mineralization technique.
PA/CS-HAP fiber achieves super hydrophilic effect.
The adsorption capacity of PA/CS-HAP in 100 mg L−1 Pb(II) reached 27.5 mg g−1.
After fitting, the adsorption process is consistent with Langmuir adsorption.
期刊介绍：
Journal of Vinyl and Additive Technology is a peer-reviewed technical publication for new work in the fields of polymer modifiers and additives, vinyl polymers and selected review papers.
