The application of carbon nanotube�metal oxide nanohybrids for the removal inorganic contaminants from water is presented. The synthesis was facilitated by the high degree of nanotube functionalization using a microwave assisted process, and a controlled assembly of iron oxide and zirconia were possible where the MWCNT served as an effective support for the oxides. Metal oxide loadings of up to 11% per carbon atom were achieved and the nanohybrids were effective in arsenic and fluoride removal to below drinking water standard levels. Adsorption isotherms and kinetic models for the nanohybrids and mechanistic aspects of the process are also presented. The research findings highlight the potential application for the use of MWCNT hybrids in environmental remediation. It is conceivable that MWCNT with appropriate surface modification can provide a platform for developing potentially useful environmental remediation tools.
