Oxidation of waters containing 100.0 mg L-1 of caffeine was conducted by a sono-Fenton treatment employing an ultrasound power of 720W at pH=3.0 and T=25°C. The catalytic action of ferrous ion was studied in a range of [Fe2+]0=0-100.0 mg L-1, using oxidant ratios of [H2O2]0=250.0 mM. The oxidation...Read more
Oxidation of waters containing 100.0 mg L-1 of caffeine was conducted by a sono-Fenton treatment employing an ultrasound power of 720W at pH=3.0 and T=25°C. The oxidizing action of hydrogen peroxide was studied in a range between [H2O2]0=0-250.0 mM, using iron ratios of 0.7 mol Fe2+/mol C8H10N4O2...Read more
Oxidation of waters containing caffeine was conducted by a sono-Fenton treatment employing an ultrasound power of 720 W at pH=3.0 and T=25°C. The catalytic action of ferrous ion was studied in a range of [Fe]=0-100.0 mg/L and oxidant concentrations between [H2O2]=0-250.0 mM. The oxidation of...Read more
