摘　　要：试样用过氧化钠熔融,用热水浸取熔融物,在乙醇存在下,加热煮沸驱除过氧化氢,定容后,过滤铁、镍、锰等沉淀与硼、铝分离,移取部分滤液分别测定硼、铝量。测定方法简便、快速,测定结果令人满意,硼的相对标准偏差≤0.74%,铝的相对标准偏差≤2.89%。The sample was melted with peroxide sodium. The liquid melt was leached in hot water. The hydrogen peroxide was lustrated by heating boiling. After constant volume,the depositions such as iron,nickel and manganese were separated from boron and aluminum by filter. The boron and aluminum contents were determined respectively by the part filtrate. The determination method is simple and rapid,and the results are satisfactory. The relative standard deviation of boron is less than 0.74% and the RSD of aluminum is less than 2.89%.
