The efficacy of the UV-H2O2 treatment to degrade the antibioticchloramphenicol (CHL) was investigated at 20°C using a low-pressure mercury lamp as UV source. A two-level factorial design was used to study the effects of initial CHL(c0 = 40-80 mg L-1) and H2O2(h0 = 20-50mM) concentrations, reaction time (t = 30-70 min) and irradiance level (I = 400-800 μW cm-2) on CHLdegradation. Under the best conditions (c0 = 40 mg L-1, h0 = 20 mM, t = 70 min, I = 800 μW cm-2), almost 96% of the antibiotic was degraded.

Abstract
The efficacy of the UV-H2O2 treatment to degrade the antibioticchloramphenicol (CHL) was investigated at 20°C using a low-pressure mercury lamp as UV source. A two-level factorial design was used to study the effects of initial CHL(c0 = 40-80 mg L-1) and H2O2(h0 = 20-50mM) concentrations, reaction time (t = 30-70 min) and irradiance level (I = 400-800 μW cm-2) on CHLdegradation. Under the best conditions (c0 = 40 mg L-1, h0 = 20 mM, t = 70 min, I = 800 μW cm-2), almost 96% of the antibiotic was degraded. No residual antibiotic activity was detected in the treated solution, thereby confirming the efficacy of the UV-H2O2 process. © (2013) Trans Tech Publications, Switzerland.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
