Research of Nano-TiO₂ Composites on Malachite Green Decolorizing Effect

Abstract:

A supporting body of diatomite-based porous ceramics was prepared by a solid-phase sintering process and low-temperature calcination process. nanoTiO₂ membrane was loaded on the carrier by the hydrolysis precipitation method and using TiCl₄ as the precursor. The influences of various parameters such as the initial concentration of malachite green, the amount of composites, and the initial pH had been investigated. Under the same test conditions, the decolorizing rate of malachite green was higher when the initial concentration was 6 mg/L, the composites dosage was 5 g/L, and the initial pH was 8 respectively. The influence mechanism of the initial concentration of malachite green, the amount of composites, and the initial pH for malachite green was discussed.
