ABSTRACT
Into the photooxidation
process, several factors such as pH, time of irradiation, dose of UV light,
lamp power, contaminant concentration, turbidity of the solution and the
presence of salts can interfere with the photodegradation of pollutants. This
research aims to evaluate the influence of salts: NaCl, MgCl2, CaCl2,
BaCl2, CuCl2, Na2SO4, MgSO4,
MnSO4, FeSO4, CuSO4, Na3PO4,
K2CrO4 and K2Cr2O7 in
concentrations of 0.0005 M, 0.005 M and 0.05 M during photodegradation of aqueous
solution of 59.5 mg/L of nitrobenzene at a pH of 2.5. It was observed that the
presence of salts such as CuCl2, CuSO4, FeSO4,
K2CrO4 and K2Cr2O7 interfere negatively in the system UV/H2O2 applied for
degradation of nitrobenzene; possibly by oxidation of Fe2+ to Fe3+ and Cu+ to Cu2+ in the Cr case, due to the difficulty of
transforming the Cr6+ to Cr3+ or because these solutions
have color and act as radiation absorbing filter.
