Fabrication of chitosan/silica nanofibrous adsorbent functionalized with amine groups for the removal of Ni(<scp>ii</scp>), Cu(<scp>ii</scp>) and Pb(<scp>ii</scp>) from aqueous solutions: batch and column studies

Abstract

Homogeneous fibers with average diameters of 90 and 138 nm were formed as pure CS and CS/TEOS/APTES nanofibers and the performance of the prepared nanofibers was investigated for Ni(<sc>ii</sc>), Cu(<sc>ii</sc>) and Pb(<sc>ii</sc>) ion sorption.
