Abstract

The photocatalytic decolorization of C.I. Basic Blue 3 (BB3) solution on immobilized TiO₂ nanoparticles was carried out in a rectangular flat-plate photoreactor. The investigated TiO₂ was Millennium PC-500 (anatase, average crystallite size 8nm, surface area 320.76m²g^-1) immobilized on non-woven paper. A new kinetic model was proposed on the basis of intrinsic element reactions. The proposed kinetic model fairly resembled the classic Langmuir-Hinshelwood (L-H) equation from its expression. It was found that both k_obs (the reaction rate constant) and K_R (the adsorption rate constant) were linearly proportional to the light intensity in a rather large intensity range.
