removal of naphthalene from wastewater using hydrodynamic cavitation

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#
