* 9661341法拉 这项小型企业创新研究第一阶段将由Montec Associates，Inc.项目提出了一种新的机械方法，以引起低频，声能驱动的空化液体作为高级氧化反应器的应用。 局部高温（5000 ℃）、高压（几百个大气压）和高剪切力已被证明发生在由超声波产生的空化气泡内。 在空化气泡的内爆期间产生的高能环境充当“微反应器”以实现和/或加速化学反应。 通过超声诱导的空化作用产生氢氧根离子和过氧化物用作侵蚀性氧化剂是有据可查的。 所提出的技术，称为共振声波，已被用于在蒙特在液体和泥浆中产生高能量的空化在低频，例如，两千赫兹。 用低频声波引起空化的能力具有深远的意义，因为它克服了严重的缩放和成本限制，这些限制阻碍了商业超声处理应用。 在Montec进行的探索性测试表明，ResonantSonics可以破坏（氧化）氰化物，并大大提高氰化物和氟化物以及重金属从污染材料中的去除。 这些探索性实验的结果为Montec开发ResonantSonics作为可行的商业高级氧化工艺提供了强大的动力。 该技术有可能提供一种可行的声化学方法，适用于有效扩大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和危险废物。 ***

*** 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. ***
