Construction of hydrophilic covalent organic frameworks and their fast and efficient adsorption of cationic dyes from aqueous solution

Abstract

Research about the functionalized covalent organic framework (COF) materials with well hydrophilic characteristics is significant on account of their application in the removal of dyes in wastewater. In this work,...

Carbon dots/silica nanoaggregates for highly efficient adsorption of alizarin red S and malachite green dyes

“…5 Among them, adsorption is the most commonly practiced method due to its ease of operation, environmental friendliness, and good reproducibility in removal processes. 6,7 In adsorption techniques, diverse categories of adsorbents have been utilized and developed to achieve highly efficient adsorption of the desired organic dyes. Among many kinds of adsorbents, carbon-based nanomaterials such as carbon dots (CDs), carbon nanotubes, carbon nanofibers, graphene and its derivatives form a new adsorbent family.…”
