Abstract:

We devise a water quality detection device with sonoluminescence principle. It includes a reaction chamber, an ultrasound driving power, a transducer and a photoelectric device. Water sample is deposited in a sample container that is connected with a water pump by a pipe. The water sample is pumped into the reaction chamber. The ultrasound power then drives the transducer. Ultrasonic luminescence phenomenon further occurs for the water sample. The light is received by a photomultiplier tube through a detection window and then converted into an electronic signal fed into a computer. We can therefore analyze the quality of the water sample by sonoluminescence principle.

Key words: sonoluminescence, water quality monitoring, device design
