Preparation of biochar@chitosan-polyethyleneimine for the efficient removal of uranium from water environment

Nickel single atom mediated phosphate functionalization of moss derived biochar effectively enhances electrochemical uranium extraction from seawater

“…In the latest research, biomass carbon has been utilized as a catalyst for electrochemical uranium extraction due to its wide availability, low cost, high surface area, and specific three-dimensional pore structure. 18,19 However, the limited electrochemical active centers and uranium coordination sites, as well as the biological damage to the catalysts by seawater, hinder their application in seawater uranium extraction. 20–22 Previous studies have found that loading single-atom active sites onto carbon materials to form metal–nitrogen–carbon (M–N–C) structures, resembling porphyrins, can significantly enhance the electrocatalytic performance and antibacterial properties of the catalysts.…”

Chitosan as a Polyfunctional Crosslinker for a Renewable-Based Resorcinol Diglycidyl Ether

“…Wang et al prepared efficient biosorbent materials based on chitosan or modified chitosan to be used in different treatment technologies for heavy metal removal from water and wastewater. The authors investigated the metal sorption ability, the influence of the nature of metal ions, and parameters affecting adsorption such as pH and contact time, together with the kinetical models and biosorption mechanisms. − …”
