Abstract
The photocatalytic degradation kinetics of three sulfa pharmaceuticals has been investigated in TiO2 aqueous suspension. The disappearance of these three compounds follows a pseudo-first-order kinetics according to the Langmuir–Hinshelwood (L–H) model. The effects of catalyst amount, initial pH value, and initial concentration of each substrate on the photocatalytic degradation rates were measured in detail. It was observed that the ...
