SONOCHEMICAL DEGRADATION OF P-NITROPHENOL IN THE PRESENCE OF CHEMICAL-COMPONENTS OF NATURAL-WATERS

The kinetics of the sonochemical degradation of p-nitrophenol have been investigated in solutions containing particulate matter, phosphate, bicarbonate, humic acid and in solutions prepared from lake water. Under conditions that are similar to those of the natural environment, the rate of p-nitrophenol degradation is the same as the decay rate in pure water. The kinetic results suggest that high-temperature denitration reactions of p-nitrophenol at the interface of cavitating bubbles are not affected by presence of chemical components of natural waters.
