本文对富离子基质中有机污染物的超声降解进行了评述。超声波能够降解富含离子的基质中各种性质的污染物。低浓度的污染物有利于在矿泉水和海水中降解。有效的污染物声降解矿泉水或海水，但在尿液中的作用是有限的。必须测试超声作用后基质的生态毒性和转化。药物、杀虫剂、染料、合成和天然激素、增塑剂和工业化学品等物质每天都进入环境。其中许多是全世界日益关切的问题。使用超声波来消除这些化合物是处理矿泉水，海水和尿液的一种有趣的替代方法。因此，这项工作提出了一个系统的和批判性的审查文献上消除有机污染物在这些特定的矩阵，使用超声波为基础的过程。声化学系统的降解效率，污染物的性质（挥发性，疏水性，或亲水性），基质效应（增强或有害的能力相比，纯水）的影响，和污染物浓度的作用被认为是。考虑了超声与其他降解过程的组合，以克服声化学过程的固有局限性。此外，还估算了与目标基质中污染物降解相关的能源消耗和能源成本。此外，在未来的工作中，应该开发的差距，在矿泉水，海水和尿液中的有机污染物的超声降解，进行了讨论。
Sonodegradation of organic pollutants in ions-rich matrices is critically reviewed. Ultrasound is able to degrade pollutants of diverse nature in ions-rich matrices. Low concentrations of contaminants favor degradation in mineral water and seawater. Efficient pollutants sonodegradation in mineral water or seawater but action in urine is limited. Ecotoxicity and transformations after ultrasound action on matrices must be tested. Substances such as pharmaceuticals, pesticides, dyes, synthetic and natural hormones, plasticizers, and industrial chemicals enter the environment daily. Many of them are a matter of growing concern worldwide. The use of ultrasound to eliminate these compounds arises as an interesting alternative for treating mineral water, seawater, and urine. Thereby, this work presents a systematic and critical review of the literature on the elimination of organic contaminants in these particular matrices, using ultrasound-based processes. The degradation efficiency of the sonochemical systems, the influence of the nature of the pollutant (volatile, hydrophobic, or hydrophilic character), matrix effects (enhancement or detrimental ability compared to pure water), and the role of the contaminant concentration were considered. The combinations of ultrasound with other degradation processes, to overcome the intrinsic limitations of the sonochemical process, were considered. Also, energy consumptions and energy costs associated with pollutants degradation in the target matrices were estimated. Moreover, the gaps that should be developed in future works, on the sonodegradation of organic contaminants in mineral water, seawater, and urine, were discussed.
