The aqueous solution pH from 2 to 5 was adjusted with 0.1 N H2SO4. Then, the designed dose of iron as Fe2+(0.09–2.13 mM) and hydrogen peroxide (5.35–17.4 mM) were added and Fenton’s reaction was initiated. After each designed reaction time (30–240 min), the treated sample was ...
The solution pH was adjusted using 1 N H2SO4 or 1 N NaOH solutions. An aliquot of the freshly prepared stock solution of H2O2 was finally added to initiate the reaction. Samples were withdrawn at predetermined times and immediately quenched by equal aliquot of methanol. Then they were ...
