Abstract

We found that sonochemiluminescence (SCL) can be used as an analytical tool to determine some pesticides. At a given ultrasonic frequency (1.7 MHz) and under suitable conditions, the collapse of the bubbles can result in light emission (sonoluminescence, SL). Hydroxyl (OH) radicals generated during bubble collapse can react with luminol to produce sonochemiluminescence (SCL). SCL intensities were recorded for several pesticides solutions and compared with their blank SCL signal. Based on the results of the comparison of the SCL intensity of luminol methanolic solution (blank signal) with the SCL intensity of methanolic solutions of pesticides (sample signal) it was established that some pesticides play an antioxidant role and can react with OH radicals and inhibit the SCL of luminol. This strategy has potential to be used for the determination of some pesticides in environmental waters.
