Abstract

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.Result: In 15 mg/L naphthalene in UV/H2O2 system and reaction times 5, 10, 20, 30, 40, 50, 60, 100 and 120 minutes, 15, 28, 31, 36, 42, 52, 56, 73 and 59.5% naphthalene removal efficiencies were observed and COD removal efficiencies in reaction times 5, 10, 20, 30, 40, 50, 60, 100 and 120 minutes, 22, 38, 45, 61.5, 67.5, 70, 80, 88.5 and 76 % were observed. When the initial pH values were 3, 4, 5, 6, 7, 9, 10 and 12 the naphthalene removal efficiency was approximately 75.8, 63.4, 62, 58.5, 44.8, 35.8 and 30%, respectively, with UV/H2O2 system.Conclusion: The experimental results of this study suggested that the dosages with 20 mg/L H2O2 at pH=3 with 2.8 W/cm2 UV intensity (254 nm) provided the optimal operation conditions for the mineralization of naphthalene yielding a 73% mineralization efficiency after 100 minutes of reaction time.
