Polyaniline-functionalized Nb₂CT_x Mxene composites for effective Cr(VI) adsorption from wastewater.

ABSTRACT: In this study Nb₂CT_x/PANI nanocomposite was reported for the adsorption of Cr(VI) from contaminated water samples for the first time. The unique structure of Nb₂CT_x Mxene, combined with the conductive and adsorptive properties of polyaniline (PANI), forms a high-surface-area composite with enhanced affinity for Cr(VI) ions. The synthesized nanocomposite was characterized by using different techniques XRD, FTIR, BET, SEM-EDX, XPS and Raman spectroscopy. Influence of various parameters such as pH, dosage, and initial ion concentration on adsorption were also studied. Adsorption experiments demonstrate that Nb₂CT_x/PANI exhibits a high adsorption capacity, achieving a maximum Cr(VI)removal efficiency of 468.35 mg/g. Freundlich m
