Desenvolvimento de metodologia eletroquímica para degradação da ciprofloxacina por agentes oxidantes gerados in situ

Abstract

Ciprofloxacin is second generation quinolones flour, which is very soluble in water. This drug can be found in Sewage Treatment Plants (STPs) and natural waters at concentrations of μg L-1 and ng L-1. Electrolysis was carried out using Ag/AgCl as reference electrode and as cathode and anode plates of Ti/TiO2 were used. To study the role of supporting electrolyte were used H2SO4, HCl, NaCl, NaNO3, KCl, and Na2SO4. Were applied current densities (DC) between 20 and 160 mA.cm-2. The electrodic process indicates be dependent on pH and ionic strength. Through electrolysis, the degradation /mineralization occurs more easily in the presence of Cl-.
