【 摘 要 】

Nanomaterials have been gaining increasing interest in the area of environmental remediation mainly due to their enhanced surface and also other specific changes in their physical, chemical and biological properties that develop due to size effects. In this work, the treatment efficiency of industrial wastewater by using Zinc Oxide Nano tubes ZnONTs, is investigated. The response of adsorption characteristics of some divalent metal ions of heavy metal contaminants of industrial wastewater such as Cadmium, Lead, and Copper towards adsorption behavior of ZnONTs at different temperatures (25, 30, 40, 50, 60, 70°C) is studied. Results show that the adsorption capacity of all tested heavy metal increase in a proportional-like trend with the increase of temperature and reaches its highest value; around 70% for Pb at 70°C as compared to Co and Cu which are about 60%, and 50%, respectively at the same temperature. By tracing these technological advances to the physicochemical properties of ZnONTs, the present research outlines the opportunities and limitations to further capitalization of these unique properties for sustainable industrial wastewater management.
