Removal of Bractive T Blue by Photodegradation and Adsorption Using ZnO
並列摘要
Bractive T Blue (BTB) partially removed from the aqueous solution at usual pH (~5.6) by adsorption on ZnO and completely removed by degradation in presence of UV light (intensity I=0.18 mW cm^(-1)) and ZnO. The removal process was monitored by recording the change of absorbance at λ_(max) = 617 nm with time. The adsorption of isotherm is of Langmuir type and the nature of adsorption seems to be electrostatic with ion exchange. The photodegradation kinetics follows the Langmuir-Hinshelwood model indicating that the degradation occurs at the surface of the ZnO particles. More than 82% color of 2.3×10^(-4) M BTB in 80.0 ml suspension contains 0.1g ZnO and vanishes in 90 minutes of illumination. Moreover, FT-IR spectral analysis does not indicate any intermediate formation during adsorption and photodegradation.
