文摘

Adsorbent filter with 3D nanofiber (NF) network was fabricated via electrospinning. NF contained hydrophilic polyacrylonitrile matrix infused with lithium ion sieves. NF adsorbent filter exhibited high water flux, low pressure requirement, and effective Li+ capture. Breakthrough studies fitted with nine well-known models reveal the suitability of Bohart-Adams. Feed can be continuously fed through the NF to collect and concentrate Li+ from aqueous resources.
