| 摘 要： | 在常温常压下，由乙二胺（EDA）和乙二醇及其衍生物（EGs）组成的混合体系可捕集SO2并转化为一种SO2储集材料（SO2SM）。EDA+EGs体系呈现了强的捕集性能（0.364~0.662 gSO2·gabsorbent-1）。FTIR，XPS和XRD结果确证了SO2SM为一种烷基亚硫酸盐。以EG-SO2SM为原料制备具有多种形貌的BaSO3或BaSO4，在此过程中，EG-SO2SM不仅提供了原材料，而且可以释放EDA和EG用作表面活性剂，调控晶体的结晶化过程。

| Abstract: | An innovative SO2 fixation into solid SO2-storage materials (SO2SMs) under mild condition was developed by employing the low-cost amine-glycol systems consisting of 1,2-ethanediamine (EDA) and ethylene glycol series (EGs). In particularly, the systems of EDA+EGs possessed a remarkable SO2 capture capability from 0.364 to 0.662 gSO2·gabsorbent-1, which formed solid SO2SMs after washing with alcohol and drying under vacuum. The resulting SO2SMs were confirmed as alkyl sulfite by extensive characterization using FTIR, XPS and XRD techniques. Subsequently, the EG-based SO2SM (EG-SO2SM) was utilized to prepare BaSO3 or BaSO4 with different morphologies. The gradual release of EDA and EG from EG-SO2SM not only yielded raw material but also generated EDA and EG that acted as efficient surfactants for the subsequent recrystallization process. |
