Application of ultrasonics to chemical analysis
- Dnepropetrovsk State Univ. (Ukraine)
Ultrasonics has found a wide utility in chemistry, making available energy densities of the order of 10{sup 3} to 10{sup 6} W/cm{sup 3}, which is 3-5 orders of magnitude greater than the energy densities used in some physical methods like radiolysis and photolysis. The paper overviews several techniques of ultrasound to chemical analysis with the greatest effect obtained by using a wide range of ultrasound frequencies. The methods described include: using different ultrasound properties like velocity of propagation, decay rate, acoustic resistance, and relaxational absorption as analytical signals; the use of sonoluminescence; applications for oxidation, coagulating, and dispersion by ultrasound methods; use of ultrasound for sample preparation; and the use of ultrasound for widening the scope of the atomic spectroscopy and electrochemcial methods of analysis.
