Batch adsorption of methyl tert-butyl ether (Mtbe) from aqueous solution by combined cnt and zeolite

Abstract

Combined zeolite and carbon nanotube (CNT), as an economic solution, were utilized in different experimental conditions for methyl tert-butyl ether (MTBE) removal from aqueous solution. The work deals with the influence of several parameters including contact time (30–600 min), pH (3–10), temperature (10°C–40°C), adsorbent concentration (0.5–10 mg/L), and adsorbate concentration (10–120 mg/L) through using a batch technique in an aqueous system. The results of the experimental data revealed that the adsorption efficiency of MTBE on combined CNT and zeolite decreased by increasing the contact time, temperature, and adsorbent concentration above 60 min, 20°C and 1.5 g/L, respectively. Therefore, the above measurements were chosen as the optimum for the removal of MTBE from the contaminated solutions. Also, any changes in the pH showed no significant effect on the adsorption capacity.
