Abstract
The acoustic signal from the sonochemical production of H2O2 in water, as measured by the intensity and the width of the second harmonic, show a sensitive and correlated dependence to the presence of small amounts (millimolar range) of an anionic surfactant (SDS) in water. The graphic shows the link from the ultrasonic reaction to the measurable quantities. New possibilities to reliably control such processes is therefore opened.
摘要
水中声化学法生产 H2O2 的声信号，通过测量二次谐波的强度和宽度，可以灵敏地、相关地反映出水中少量（毫摩尔级）阴离子表面活性剂（SDS）的存在。该图显示了从超声波反应到可测量量的联系。因此，为可靠地控制此类过程开辟了新的可能性。
