چکیده انگلیسی

Ultrasonic wave of frequency 1.1 MHz was used to study the sonoluminescence (SL) in air saturated water at temperatures ranging from 283 to 313 K. It has been found that the logarithm of the detected SL intensity increases linearly with the dissolved oxygen (DO) concentration. The waters with five kinds of anions in different concentration (103 μg/l): Cl− (5–25), NO−3 (0.2-1.8), F− (0.1–2.7), HCO−3 (8–15), SO2−4 (0.4–40) were used to simulate natural environmental chemistry background. The experimental results show that the anions in the simulated waters have no influence on the SL intensity measured. Based on the results a new type of DO monitoring method could be developed.
