ABSTRACT
Removal of persistent organic pollutants (POPs) from various components of the environment is an important issue, which currently much attention is paid to. Conventional methods used for their elimination are often ineffective and require additional solutions. For this reason, studies are being conducted on the possibility of using advanced methods of oxidation, which also includes ultrasonic waves. The work includes an assessment of the applicability of the sonochemical method to the oxidation of dibutyl phthalate. Presents results of tests on the effectiveness of the ultrasonic field with a fixed frequency of 20 kHz. The effect of pH, sonication time and amplitude on the process of decomposition were investigated. To the isolation of analyte was used solid phase extraction (SPE). The degree of reduction of dibutyl phthalate was determined using gas chromatography coupled with mass spectrometry (GC-MS). Preliminary studies have shown the efficacy of the use of ultrasound to remove of dibutyl phthalate.
