摘要
使用MARS-5微波高压消解系统采用HCI或HNO_3成功地溶解了α-Al_2O_3样品,指出当溶剂温度上升至240℃时,HCI或HNO_3对α-Al_2O_3样品具有较强的溶解能力.当溶剂量固定时,样品量的大小与溶样时间大致成正比关系. Al_2O_3样品中α相比率越高,消解时间越长.
A method for the acid (HC1 or HNO_3)dissolution ofα-Al_2O_3 by MARS-5 microwave digestion system was proposed. When the temperature of digestion system increased to 240℃,α-Al2O3 sample was dissolved by HC1 or HNO3. When the digestion reagent mass was constant, the digestion time was directly proportional to the sample mass. The digestion time was prolonged when the ratio of α-phase in Al2O3 sample was increased.
