*** 9661341 Farrar This Small Business Innovative Research Phase I to be carried Montec Associates, Inc. project presents a novel mechanical method to cause low-frequency, sonic-energy driven cavitation of liquids for application as an advanced oxidation reactor. Local high temperatures (5000 C), high pressures (several hundred atmospheres) and high shear forces have been demonstrated to occur within cavitation bubbles generated by ultrasonics. The high energy environment created during implosion of the cavitation bubble acts as a "microreactor" to enable and/or to accelerate chemical reactions. The production of hydroxyl ions and peroxide for use as an aggressive oxidant via ultrasonically induced cavitation is well documented. The proposed technology, termed ResonantSonics, has been used at Montec to produce highly energetic cavitation in liquids and slurries at low-frequencies, e.g., 2000 Hertz. The ability to cause cavitation with low-frequency sonics has profound implications, as it overcomes the severe scaling and cost restrictions that have prevented the commercial ultrasonic processing applications. Exploratory tests conducted at Montec have demonstrated that ResonantSonics can destroy (oxidize) cyanide and greatly enhance removal of cyanide and fluoride, as well as heavy metals, from contaminated materials. The results of these exploratory experiments provide a strong motivation for Montec to develop ResonantSonics as a viable commercial advanced oxidation process. The technology has the potential to provide a viable, sonochemical means, suitable for efficient scale-up to destroy or convert a broad range of hazardous waste types. Commercial applications are numerous and include treatment of mixed and hazardous wastes at government and industrial sites. ***

*9661341 Farrar这项将进行的小企业创新研究第一阶段蒙特克伙伴公司的项目提出了一种新的机械方法，使液体产生低频、音能驱动的空化，作为高级氧化反应堆应用。局部高温(5000摄氏度)、高压(数百个大气压)和高剪切力已被证明发生在超声波产生的空化气泡中。在空化气泡内爆过程中产生的高能环境就像一个“微反应器”，使化学反应得以实现和/或加速。通过超声诱导空化产生用作侵蚀性氧化剂的羟基离子和过氧化氢是有充分证据的。这项名为ResonantSonics的拟议技术已在蒙特克用于在液体和浆液中以2000赫兹的低频产生高能量的空化。利用低频声学产生空化的能力具有深远的意义，因为它克服了阻碍商业超声处理应用的严格的比例和成本限制。在Montec进行的探索性测试表明，ResonantSonics可以破坏(氧化)氰化物，并大大增强对受污染材料中氰化物和氟化物以及重金属的去除。这些探索性实验的结果为Montec开发ResonantSonics作为一种可行的商业高级氧化工艺提供了强大的动力。这项技术有可能提供一种可行的声化学手段，适用于有效扩大规模，以销毁或转化广泛的危险废物类型。商业应用很多，包括在政府和工业场所处理混合废物和危险废物。***
