Synthesis of NanoTiO₂/CTMAB-Expanded Perlite Applied to the Degradation of Methyl Orange

Abstract:

Different environmental remediation materials were prepared by using Cetyltrimethylammonium Bromide (CTMAB) and/or TiO₂ to surface-modify expanded perlite (EP). Photocatalytic degradation of Methyl Orange in polluted water by these materials (CTMAB-EP, TiO₂/CTMAB-EP, TiO₂-EP and EP), adsorption/ degradation kinetics and relevant factors affecting degradation effects were studied. The results showed that EP had little ability to remove Methyl Orange in water, while EP modified with CTMAB and/or TiO₂ could remove Methyl Orange (MO) significantly, and TiO₂/CTMAB-EP treatment showed the highest removal rate in all treatments. Removal effects of the materials were influenced by dosage of material, shaking time and initial concentration of MO in water. These results indicated that nanoTiO₂/CTMAB-Expanded perlite can be used as a new and promising environmental remediation material in efficient removal of organic pollutant from environment.
