Removal of Malachite Green Dye from Water Using MXene (Ti3C2) Nanosheets

In the present study, new emerging 2D Mxene nanosheets (MXNSs) were synthesized from MAX phase powders of Ti3AlC2 and then characterized using a scanning electron microscope (SEM) X-ray diffraction (XRD) to explore chemical physical properties prepared MXNS. The characterization MXNS indicated formation exfoliated MXene (Ti3C2) as result HF treatment phase, which was confirmed by XRD measurements, characteristic peaks only observed. used solid adsorbent for removing malachite green dye (MG) water. effects different operational factors such dose, solution temperature, time, MG concentration, pH, ionic strength have also been evaluated. adsorption results showed that temperature solution, well its significantly influenced removal when optimum obtained within 150 min, with 20 mg at ambient pH value 6.0. maximum capacity 4.6 per g 5 efficacy 46.0%, minimum 2.5 99.1%. Finally, displayed able absorb high percentage maintained reasonable efficiency four consecutive cycles, indicating could be promising in wastewater remediation environmental sustainability.
