摘要
超声波技术作为一种物理手段和工具,能够在化学反应常用的介质中产生一系列接近于极端的条件,这种能量不仅能够激发或促进许多化学反应、加快化学反应速度,甚至还可以改变某些化学反应的方向,产生一些令人意想不到的效果和奇迹。目前对超声化学的研究已涉及到化学、材料学、环保等许多领域。本文介绍了超声化学的基本原理及其在有机合成、治理难生物降解有毒有机污染物方面的应用。
Sonochemistry has increased in interest in the past few years.The propagation of a power ultrasound wave trough a lipuid initiates a lttle-known phenomenon called acoustic cavitation.Inceptions and germs grow into bubbles which collapse,possibly giving rise to extreme conditions of temperature and pressure.These conditions initiate and greatly enhance chemical reactions.Sonochemistry can be used both in synthesize and degradation of chemical compounds.The principal and applications of sonochemical reactions were discussed in this article.
