BACKGROUND: Thiabendazole, imazalil and acetamiprid, pesticides found in wastewater in the citrus fruit processing industry, are recalcitrant to biological treatments. This study deals with the preparation of TiO 2 supported on glass beads and its use as a photocatalyst in a compound parabolic collector (CPC) solar reactor for the elimination of a mixture of these pesticides (100 μg L −1 each) in different water matrices.

Organic dyes constitute one of the largest groups of wastewater's pollutants. In general, they are released into the environment by textile industries. "pproximately , dyes are widely used in the textile industry, and a large wastewater of dyestuff is generated annually. "mong these, indigoid class is commercial dyes used mostly for cotton cloth dyeing. Indigo carmine IC is also one of the oldest dyes and still one of the most used in textile industry and is considered as a very toxic indigoid dye. Most toxic dyes are recalcitrant to biodegradation, causing a decrease in the efficiency of biological wastewater treatment plants. Titanium dioxide is a well-known photocatalyst mostly used in suspensions in photoreactions for wastewater treatment. The use of TiO has some advantages such as ease of handling, low cost, low toxicity, high photochemical reactivity, and nonspecific oxidative attack ability. In this way, it can promote the degradation of different target organic compounds with little change of operational parameters. The aim of this chapter is to present the different approaches already used in our team for the remediation of waters containing IC mainly through heterogeneous photocatalysis with TiO . "dsorption over activated carbon "C and photocatalytic degradation of IC mediated by titanium dioxide will be revised as well as some studies on the phototoxicity of the photoproducts with aquatic and terrestrial organisms. This chapter makes a comprehensive approach to the different results on the remediation of model effluents containing IC undertaken by this team of researchers.

Photochemical degradation contributes to the environmental fate of many pesticides in surface waters. A better understanding of the role of direct and indirect photochemical degradation of pesticides is necessary in order to predict their environmental fate and persistence. This review includes all major pesticide classes and focuses on the importance of dissolved organic matter (DOM) as a sensitizer in indirect photodegradation within aquatic systems. Photochemical studies conducted under environmentally relevant conditions (i.e., aqueous solutions with irradiation wavelengths >290 nm) are included. Comparisons are made between observed photodegradation rates in pure or buffered water and in water containing DOM to assess the extent of pesticide susceptibility to DOM-sensitized indirect photolysis. When data is available, the role of specific reactive species in indirect photodegradation is described. While it is possible to assess the relative importance of direct and indirect photodegradation on a pesticide-by-pesticide basis in many cases, it is often difficult to make generalizations based on compound class. Knowledge gaps and inconstancies in the current body of literature are discussed and areas that require additional research are described.
