Elimination of Cd2+ from synthetic and real polluted water by optimized Acacia nilotica biographene

Applied Water Science, Journal Year: 2024, Volume and Issue: 14(10)

Published: Oct. 1, 2024

Abstract Biographene was prepared through the pyrolysis of Acacia nilotica waste using diverse temperatures and time spans. The obtained materials were characterized scanning electron microscope (SEM), transmission microscopy (TEM), energy-dispersive X-ray spectrometry (EDX), diffraction analysis (XRD), Fourier transform infrared spectroscopy (FTIR) methods. data indicated that when temperature increased, texture biographene became more porous with greater carbon content. effect various variables on Cd(II) adsorption, optimized product, investigated, results revealed optimum pH 4 maximum adsorption capacity 118.9 mg/g. Langmuir isotherm model pseudo-second-order kinetic best fit equilibrium data, indicating adsorptive behavior as-prepared implying a homogenous monolayer surface. recyclability investigation elucidates remarkable potentiality up to five consecutive cycles. As such, biographene-based could be considered sustainable candidate for cadmium removal from polluted water.
