【摘要】 在气溶胶泄漏研究中涉及纤维素滤纸、玻纤滤材、膨润土和砂中铽的含量分析。本工作采用微波密闭消解法作为这些样品分析的前处理 ,并优选了消解试剂及用量、消解压力及消解时间等条件 ,建立了前处理流程。用 ICP-AES分析 Tb的含量 ,结果表明回收率为 65 %— 98% ,待测元素 Tb和内标元素 Lu的回收率比值为 1 .0 0± 0 .0 5更多还原

【Abstract】 Analysis of terbium in filter paper, glass fibrous filter, bentonite and sands was needed in study on aerosol leakage, so microwave digestion technique was utilized as pretreatment method.The experiment conditions such as acids used in dissolution, the dose of the acids,digestion pressure and digestion time were optimized, and a pretreatment procedure was set up. The ICP-AES results indicate that the recovery is 65%-98% and the recovery yield of terbium and lutetium is 1.00±0.05.更多还原
