Abstract
This chapter deals with the use of sunlight to produce •OH radicals by photocatalysis and its application to the removal of pesticides from water. The systems necessary for performing solar photocatalysis based on compound parabolic collectors are described and it outlines the basic components of these plants. It reports a step-by-step research methodology describing the analytical tools to infer the reaction mechanisms, pathway and kinetics and the application of various techniques for determining biodegradability and toxicity. Besides, it underlines the importance of: (i) using acute toxicity bioassays, for stating biocompatibility of the treated water with the environment and (ii) using photocatalysis as a pre-treatment step, if the intermediates resulting from the reaction are readily degraded by microorganisms (biotreatment).
