Decolouration of Acid Red 27 (AR27) was investigated using UV irradiation in the presence of SnO2 nanoparticles synthesized via the hydrothermal method. The average crystallite size of SnO2 nanoparticles synthesized for 2 h was about 3.73 nm, according to X-ray analysis, and the specific surface area, which was estimated from the Halsey based t plot, was about 288 m2/g. The effects of UV irradiation in the absence of a photocatalyst and in the presence of pure SnO2 nanoparticles without any light source were negligible. An artificial neural network (ANN) was used to build an empirical model for the results. The results of neural network analysis are in good agreement with the experimental data which show that AR27 decolouration exhibits pseudo-first-order kinetic behaviour.
