Ultrasonic irradiation a chlorinated organic compounds (Trichloroethylene, Tetrachloroethene, 1, 1, 2-Trichloroethane) from water

The paper describe the sonochemical degradation of organochlorine compounds (Trichloroethylene,
Tetrachloroethene and 1, 1, 2-Trichloroethane) from aqueous solutions. The experiments was realized with
two types of equipment: ultrasound bath UCD-150 and sonotrode UP 200 Ht. The experimental results
showed high efficient removal for all three compounds: Tetrachloroethene 93.8%, 1, 1, 2-Trichloroethane
92.9% and Trichloroethylene 86.6% in bath ultrasound treatment after 50 min. The ultrasound efficiency
treatment depend by the sonotronde diameter. The degradation of Trichlorethylene and 1, 1, 2 -Trichloroethane
is much better for sonotrode with 14 mm diameter (92.1% respectively 92.7%) than for sonotrode with 40
mm diameter (71.9% and 61.6%), while for Tetrachloroethene values were very close, 88.7% respectively
89.4% for the same above mentioned diameters.
