Preparation of TiO2-HZSM-5 Composite Used For Removal of Active Brilliant Red X-3B

摘要

A composite of TiO2 and HZSM-5 zeolite was used for adsorption and photocatalytic degradation of Active Brilliant Red X-3B.The composite was prepared by solid state dispersion method.Decoloration rate increased with increasing TiO2 content to the maximum value of 80％ at TiO2 content of 10％.After that,decoloration rate declined as continuing increase of TiO2 content.Adsorption of ABR X-3B on the composite had very small change and the maximum adsorption rate was not more than 5％ with the variation of TiO2 content.Photocatalytic degradation varied drastically with change of TiO2 content.The optimum TiO2 content was 10％ as under consideration of its adsorption and photocatalytic degradation activity.
