Advances In Sonochemistry

This is the fifth volume of Advances in Sonochemistry the first having been published in 1990. The definition of sonochemistry has developed to include not only the ways in which ultrsound has been harnessed to effect chemistry but also its uses in material processing. Subjects included range from chemical dosimetry to ultrasound in microbiology to ultrasound in the extraction of plant materials and in leather technology.

Advances in Sonochemistry

Ultrasound in Environmental Protection focuses on one of the more significant developments in the subject - environmental remediation - providing an overview on both the fundamentals and applications of ultrasound in environmental protection, incorporating recent research and state-of-the-art information on the scientific basis, modes of use, and engineering developments. A broad spectrum of topics are covered: reactor design, sonochemical pollutant degradation, integrated unltrasonic/ biological treatment, ultrasound in disinfection, leaching by ultrasound, and ultrasonically enhanced removal of suspended solids. Ultrasound is generated and applied at frequencies from 20 kHz to several MHz. The physio-chemical parameters of the sonicated media, reactor design, applied intensity, and duration of sonication, dramatically influence the effects that can be achieved. It is hoped that this compilation will contribute to a better understanding and further development of sonochemistry as a clean technology not only for environmental remediation but also more generally. The foundation of this compilation was formed during a workshop that was held at the Technical University of Hamburg-Harburg, Germany, in March 1999. This was the first workshop to be devoted to 'Ultrasound in Environmental Engineering' and brought together experience and knowledge from a broad spectrum of disciplines including chemistry, biology, engineering, equipment manufacturing, and plant design.

This updated version of Practical Sonochemistry for advanced students and teachers in chemistry and chemical engineering conveys the increasing growth in applications and equipment to power ultrasound. Equipment now on the market offers a wider range of frequencies with more reproducible experimentation and a variety of scale-up systems. The book provides detailed descriptions of newer ultrasonic equipment and its applications, and practical laboratory uses of ultrasound technology for industrial scale performance. Modern exercises familiarise readers with recent sonochemical operations. The book also includes methods for estimating ultrasonic energy entering the system (dosimetry), which will standardise sonochemical methodology and enable practitioners to reproduce results from other laboratories.

This book provides up-to-date coverage of the latest research in this still relatively new area and includes an introductory chapter to assist newcomers to the subject.
