Preparation and properties of the photocatalytic-active membrane with immobilized TiO2 for water treatment from phenol and its derivatives
Анотація
A method of preparation and properties of a photocatalytic-active membrane with deposited TiO2 for water treatment from phenol and its derivatives have been developed and studied in the work. Ceramic membrane based on γ-Al2O3 was found to be the optimum porous support for immobilization of the catalyst. The comparison of various approaches for deposition of TiO2 active layer on the porous ceramic support was performed. It has been shown that the catalytic-active membrane obtained provides a high degree of water purification (99.4 – 99.9 %) not only from phenol, but also from its derivatives (hydroquinone, p-chlorophenol, and n-nitrophenol) at rather short time of water treatment (1.5 – 2 h). The efficiency of water purification was found to depend essentially on solution pH value.
