Hydroxyl radicals and hydrogen atoms were produced in argon-saturated aqueous solutions exposed to ultrasound using clinical dental equipment. .OH and .H radicals were detected and identified by ESR and were spin trapped with 5,5-dimethyl-1-delta-pyrroline-N-oxide (DMPO) and alpha-4-pyridyl-1-oxide-N-tert-butylnitrone (POBN). The observed ESR spectra were compared with those obtained from sonolysis of argon-saturated water in an ultrasonic bath, from gamma radiolysis of air-saturated water, and from uv photolysis of aqueous hydrogen peroxide solutions.
使用临床牙科设备，在暴露于超声的氩饱和水溶液中产生了羟基自由基和氢原子。通过电子自旋共振（ESR）检测并识别了·OH和·H自由基，并用5,5-二甲基-1-δ-吡咯啉-N-氧化物（DMPO）和α-4-吡啶基-1-氧化物-N-叔丁基硝酮（POBN）进行自旋捕获。将观察到的ESR光谱与在超声浴中氩饱和水的声解、空气饱和水的γ辐解以及过氧化氢水溶液的紫外光解所获得的光谱进行了比较。
