AI Technical Summary
Technical Problem
Existing nanofibers have low removal efficiency for nickel complexes, high processing costs, limited recycling performance, and pose a risk of secondary pollution. Furthermore, nickel ion resource recovery is difficult.
Method used
Using polyvinyl alcohol, polyaniline, and polyacrylonitrile as raw materials, amine- and sulfur-containing nanofiber adsorbent materials are prepared by electrospinning technology. These materials are used for the deep removal of nickel complexes in water, and the nickel ions are recycled through desorption solution to achieve resource utilization.
Benefits of technology
This improved the removal efficiency of nickel complexes, reduced treatment costs, decreased the risk of secondary pollution, and enabled the resource utilization of nickel ions.
