摘要：
In this paper the synthesis, characterization and testing of composite material based on multi-wall carbon nanotubes and silver-doped natural zeolite (MWCNT-ZAg) has been investigated for humic acid (HA) adsorption. The surface characterization of the composite material has been investigated by X-ray diffraction (XRD) and scanning electron microscopy (SEM/EDX) analysis. The Langmuir and Dubinin-Radushkevich (D-R) models fitted the best experimental data informing that adsorption process of HA onto MWCNT-ZAg is heterogeneously and well described by the pseudo-second-order kinetics. The adsorption results confirmed that MWCNT-ZAg composite can be used as a promising sorbent for the adsorptive HA removal in water treatment process.
