Kinetic studies of 2-chlorophenol photocatalytic degradation are carried out in a batch stirred built in quartz laboratory scale, using TiO2 as catalyst photoactived with ultraviolet light. Experimental design is performed using as independent variables or factors: catalyst concentration, catalyst calcinations temperature and initial concentration of 2-chlorophenol, to establish the best conditions of the degradation process. The experimental data were fitted with the Langmuir-Hinshelwood model...

The experimental data were fitted with the Langmuir-Hinshelwood model. A kinetic constant k of 0.24 mg L-1min-1 was obtained.
