Abstract

The inactivation of Fusarium solani in water was assessed by solar driven Fenton-like processes usingthree different iron salts: ferric acetylacetonate (Fe(acac)3), ferric chloride (FeCl3) and ferrous sulfate(FeSO4). The experimental conditions tested were [Fe] z 5 mg L�1, [H2O2] z 10 mg L�1 and[Fe] z 10 mg L�1; [H2O2] z 20 mg L�1 mild and high, respectively, and pH 3.0 and 5.0, under solarradiation. The highest inactivation rates were observed at high reaction conditions for the three iron saltstested at pH 5.0 with less than 3.0 kJ L�1 of accumulate energy (QUV) to achieve over 99.9% of F. solaniinactivation. Fe(acac)3 was the best iron salt to accomplishing F. solani inactivation. The modified Fermiequation was used to fix the experimental inactivation, data showed it was helpful for modeling theprocess, adequately describing doseeresponse curves. Inactivation process using FeSO4 at pH 3.0 wasmodeled fairly with r2 ¼ 0.98 and 0.99 (mild and high concentration, respectively). Fe(acac)3, FeCl3 andFeSO4 at high concentration (i.e. [Fe] z 10 mg L�1; [H2O2] z 20 mg L�1) and pH 5.0 showed the highestfitting values (r2 ¼ 0.99). Iron salt type showed a remarkable influence on the Fenton-like inactivationprocess.
