Abstract:
The use of 2D metal carbides, nitrides and carbonitrides (MXenes) in the treatment of heavy metals is becoming more and more widespread. MXenes have strong chemical compatibility, greater thermal stability, outstanding surface adjustable chemical compatibility, hydrophilicity, ease of functionalization, large surface area and biodegradable features. The oxidizing functional groups and accessible active binding sites of MXene nanoparticles make them a special adsorbent for eliminating heavy metals from waste-water because of their distinctive layered structure. Batchmode investigations were carried out to ascertain the impact of several factors such as contact duration, adsorbent dosage, sample pH, temperature and initial concentration of polluted water on the adsorption of Cadmium (II). MXene was subjected to FTIR, XRD, BET, EDS, and SEM analysis both before and after the adsorption procedure in order to understand the surface properties and validate the adsorption of Cadmium (II) over MXene. Using batch adsorption with optimum conditions, including pH is 6.0, adsorbent dosage is 0.015 g/ 50mL, contaminated water concentration is 250 mgL-1, temperature is 30oC, agitation, and contact duration of 30 minutes, MXene was able to remove Cadmium (II) with a maximum removal rate of 95.43%. Data fitting with the Langmuir isotherm and good correlation with the pseudo-second order were explained by the performed adsorption kinetics studies and adsorption isotherms. Therefore, it can be said that MXene is a suitable adsorbent for remediation of Cadmium (II) metal ions from waste-water.
