| Popis: | In the present research, we propose a novel measuring method of ultrasonic cavitation by naked-eye based on the conversion of ferrous ion to ferric ion and chromogenic reaction between ferric and thiocyanate. The effects of different conditions affecting cavitation were investigated. Experiments show that this method can effectively measure the strength of the cavitation field of the system, and is simple to operate, and the results are intuitive, and the cavitation strength can be obtained quickly. The effects of size and concentration of solid particles on ultrasonic cavitation are also studied by using micro-SiO2 as the typical representativeness. It was found that the addition of solid particles could reduce the heterogeneous cavitation threshold. The results provide a basis for the industrialization of ultrasonic chemistry, especially the strengthening of the reaction process of heterogeneous systems under ultrasound. |
