Sonophotocatalytic degradation of eriochrome black-T dye in water using Ti grafted SBA-15
Source abstract
Abstract
Here in, a series of titanium-modified mesoporous silica (Ti-SBA-15) was prepared by grafting titanium isopropoxide. The as-synthesized Ti-SBA-15 nanocatalysts were characterized through N2-adsorption–desorption, XRD, TGA/DSC, TEM and EDX techniques. Sonocatalytic and sonophoto-catalytic degradation of Eriochrome Black T (EBT) dye were investigated. 88.7 % removal was achieved in 70 min by using 5 % Ti-SBA-15 through sonophotocatalytic degradation under visible light irradiation. The kinetic study revealed that photo-degradation of EBT follows pseudo-first order reaction mechanism, where the rate constant was 27.4 × 10−3 min−1.
