Abstract

Heavy metals are toxic for human and animals. Industrial wastewater streams containing heavy metals are produced from different industries. CLINOPTILOLITE (CP) (Iranian domestic Natural Zeolite) was modified by titanium oxide and iron oxide NANOPARTICLES using solid-state dispersion (SSD) method. These NANOPARTICLES of the adsorbent were characterized by BET, XRD, SEM, and EDS. Various factors affecting the uptake behavior such as contact time, initial concentration of Pb2+, dosage TIO2-Fe3O4/CP, pH, temperature, and shaker rate were investigated. The maximum effect of adsorbent was observed at 5 wt. % TIO2, 5 wt. % Fe3O4, and 90 wt. % CLINOPTILOLITE. The equilibrium data were analyzed using Freundlich and Langmuir isotherms and the Langmuir ADSORPTION capacity was found to be 109.89mgg-1. Thermodynamic parameters showed that the ADSORPTION process was endothermic from 283 to 313 K, then it was exothermic from 323 to 333 K. The kinetics followed is first order in nature, and the value of rate constant was found to be 0.0093 min-1 at 100 ppm and 303 K.
