摘要
样品经微波消解及在线稀释进样,采用火焰原子吸收光谱法测定锂电池中锂的含量。在优化的试验条件下,锂的线性范围为0.01～2.5 mg·L^(-1)。该法用于测定锂电池中锂的含量,回收率在94.0%～104.0%之间,相对标准偏差(n=7)在1.6%～4.5%之间。
The sample of lithium cell was treated with microwave digestion system and the sample solution was introduced by on-line dilution system.The content of lithium was determined by AAS.Under the optimized conditions,linearity range of lithium was kept from 0.01 mg·L^-1 to 2.5 mg·L^-1.The proposed method was applied to the determination of lithium in lithium cell,giving values of recovery in the range of 94.0%-104.0%and RSD（n=7） in the range of 1.6%-4.5%.
