Effect of UV/H2O2 advanced oxidation processes for the removal of naphthalene from the water solution

Background: Naphthalene is a polyaromatic hydrocarbon (PAHs) present in many water sediments. This study evaluated the performance of UV/H2O2 reaction to decompose naphthalene in the aqueous solution. Material and method: It was an experimental-laboratory study. A one liter cylindrical glass reactor was used for performing all degradation experiments. The radiation source was a low pressure mercury UV lamp emitting at 254 nm (30 W, UV-C) which was placed above a batch photoreactor for UV/H2O2 experiments and different concentrations of H2O2 (5, 10, 15, 20, 25 and 30 mg/L) were tested.
