Ethylbenzene Removal by Carbon Nano tubes from Aqueous Solution

The removal of ethylbenzene (E) from aqueous solution by multi walled, single-walled, and hybrid carbon nano tubes (MWCNTs, SWCNTs, and HCNTs) was evaluated for a nano material dose of 1 g/L, concentration of 10-100 mg/L, and ph 7. The equilibrium amount removed by SWCNTs (E: 9.98?mg/g) was higher than by MWCNTs and HCNTs. Ethylbenzene has a higher adsorption tendency on CNTs, so that more than 98% of it adsorbed in first 14 min, which is related to the low water solubility and the high molecular weight. The SWCNTs performed better for ethylbenzene sorption than the HCNTs and MWCNTs. Isotherms study indicates that the BET isotherm expression provides the best fit for ethylbenzene sorption by SWCNTs. Carbon nano tubes, specially SWCNTs, are efficient and rapid adsorbents for ethylbenzene which possess good potential applications to maintain high-quality water. Therefore, it could be used for cleaning up environmental pollution to prevent ethylbenzene borne diseases
