Mechanochemical Decomposition of Dipotassium Peroxodisulfate by Dry Grinding
摘要:
通过 X 射线衍射、红外分光光度法、电子自旋共振 (ESR) 光谱以及热分析和体积分析研究了干磨过二硫酸二钾的机械化学分解。当过二硫酸二钾(K2S2O8)被研磨时,K2S2O8的I型转变为II型,然后转变为III型。随着长时间的研磨,K2S2O8中的O-O键被切断,产生KSO4·自由基,其与少量水分反应生成KHSO4。
The mechanochemical decomposition of dipotassium peroxodisulfate by dry grinding was investigated by X-ray diffractometry, infrared spectrophotometry, electron spin resonance (ESR) spectrometry, and thermal and volumetric analyses. When dipotassium peroxodisulfate (K2S2O8) was ground, type I of K2S2O8 was transformed into type II and then into type III. With prolonged grinding, the O–O linkage in K2S2O8 was severed to produce KSO4· radicals, which reacted with a little moisture to give KHSO4.
