RESUMO
Ivermectin is widely used as an antiparasitic agent against endo and ectoparasites of animaIs and humans; it has a broad spectrum of activity at low dosage levels. Commercial products (Ivomec@, Eqvalan@, Cardomec@~ Mectizan~ usually contain 1% of Ivermectin in glycerol formulation. Ivermectin is a rnixture oftwo homologs containing more than 80% Avermectin B1a [C48H74014]~ and less than 20% Avermectin B1b[C47H72014], with 871.10 and 861.10 molecular weights respectively. As the compounds present high molecular weight, the conventional biological treatment is not efficient for their degradation. The current methods of Ivermectin degradation are incineration or alkaline hidrolysis at high temperatures. In this study, industrial samples of wastewater ftom a veterinary industry, containing Ivermectin, ftom the region ofCampinas were collected. The main goal ofthe present study w~ to develop and to optimize a photoelectrochemical reactor , in a pilot scale, for the treatment oj eftluent containing Ivermectin. The photoelectrochemical treatment was carried out in a flow cefi reactor, and commercia DSA@ type electrodes with nominal composition of 70Ti02/ 30Ru02~ were used as anodes, and ~ Ti screen as cathode
