Abstract Homogeneous photocatalysis by photo-Fenton processes has been applied to the degradation of six water-soluble pesticides (alachlor, atrazine, chlorfenvinphos, diuron, isoproturon and pentachlorophenol), considered priority substances by the European Union Water Framework Directive (Directive 2000/60/EC). All tests were performed in a 35-L solar pilot plant with compound parabolic collectors (CPCs) under natural sunlight. The initial concentration tested for all the compounds was 50 mg/L except for those less soluble in water. Two different concentrations of iron were tested, 2 mg/L and 1 mM. All pesticides were successfully degraded and substantially mineralised. Total dechlorination was clearly attained more quickly than 90% of mineralisation in all cases. Several operating parameters, treatment time, hydrogen peroxide consumption and iron concentration, involved in the degradation of the parent compounds and their mineralisation are discussed.
