Sonochemical degradation of the following organochlorine compounds: 1,2 dichloropropane, 1,1,2-trichloroethane, 2 ethylhexanol and b, b’---dichlorodiisopropyl ether was carried out. The experiments was realized with two types of equipment: ultrasound bath UCD-150 and sonotrode UP 200 Ht. Experimental results showed high efficient removal for all compounds: 1,1,2- trichloroethane and b, b’-dichlorodiisopropyl ether 78.0%, 1,2 Dichloropropane 66.0%, 2 ethylhexanol 35.0 % in bath ultrasound treatment after 60 minutes. Degradation of b, b’-dichlorodiisopropyl ether, 1,1,2-trichloroethane, 1,2 dichloropropane and 2 ethylhexanol performed much better for sonotrode with 14 mm diameter (89.0%, 77.5%, 73.0%, respectively 73.0%) than for sonotrode with 40 mm diameter (64.0%, 64.0%, 53.0% and 48.0%). This difference between the two probes regarding removal efficiency can be explained by different amplitudes of equipment."en-USOrganochlorine compoundsUltrasonic irradiationSonochemical processesWastewaterConference paper10.21698/simi.2017.0015
