To effectively utilize ultrasound, it is crucial to identify materials and media that facilitate optimal penetration. Extraction and aluminum foil erosion experiments were performed using beakers made of glass, stainless steel, and various plastics (PE, PFA, and PTFE) under different ultrasonic conditions. Additionally, ultrasound-assisted chromatography was conducted in six solutions with varying surface tensions: water, alcohol, 6% and 17% NaOH, and 20% and 35% sucrose in water. The results of the extraction and erosion experiments indicated that glass demonstrated the highest extraction efficiency and the strongest physical effects, with minimal ultrasound energy attenuation, particularly under sweep mode and low-frequency conditions. In chromatography, the findings showed that ultrasound transmission was more effective in a 6% NaOH aqueous solution compared to water.
为了有效利用超声波，识别有助于实现最佳穿透的材料和介质至关重要。在不同超声条件下，使用玻璃、不锈钢和各种塑料（PE、PFA和PTFE）制成的烧杯进行了萃取和铝箔侵蚀实验。此外，在六种具有不同表面张力的溶液中进行了超声辅助色谱分析：水、酒精、6%和17%的NaOH以及水中20%和35%的蔗糖。萃取和侵蚀实验结果表明，玻璃表现出最高的萃取效率和最强的物理效应，超声能量衰减最小，特别是在扫描模式和低频条件下。在色谱分析中，结果表明，与水相比，在6%的NaOH水溶液中超声传输更有效。
