Abstract
Naphthalene is a polycyclic aromatic hydrocarbon that has mutagenic and carcinogenic effects on humans and aquatics. It can be harmful and is considered as a pollutant of environment. In this work, degradation of naphthalene was investigated by the use of hydrodynamic cavitation (HC) for the first time. A maximum degradation of 90% with the Pseudo-first order rate constants of 3.85 × 10-2 min-1 was achieved for the degradation of 25 mg L-1 naphthalene using the method in the Pinlet of 6 bar, the temperature of 35±2°C and the natural pH. The yield efficiency of 1.6 × 10-3 mg kJ-1 was achieved in this investigation.
