Key Points

The study aims to develop a PEI/MXene adsorbent for effective chromium removal from wastewater.
Synthesis of PEI/MXene via grafting method
Characterization of adsorbent properties
Evaluation of adsorption capacity for Cr(VI)
Analysis of mechanisms behind enhanced removal
PEI modification significantly increased adsorption capacity for Cr(VI)
Adsorbent showed rapid reduction and removal in aqueous solutions
Enhanced removal attributed to abundant amino groups as active sites

Abstract

A novel PEI/MXene adsorbent was synthesized via a facile grafting method to enhance the removal of Cr(VI) from wastewater. The PEI modification introduced abundant amino groups as active adsorption sites,...
