摘要
应用空气 乙炔火焰原子吸收法连续测定镉镍电池浸渍液中铁、钾、钙 ,并对测定条件、干扰因素进行了综合考虑。该方法灵敏度高、干扰少、选择性和重现性好。相对标准偏差小于 1.0 % ,标准加入回收率均在 97%～ 10 2 %范围内。这种方法完全适用于镉镍电池浸渍液中铁、钾、钙的控制分析和样品系统分析。
Iron, potassium and calcium in Ni-Cd battery impregnating solution were continuously measured by the atomic absorbing method of air-acetylene flame, and the testing conditions and disturbing factors were investigated. The measuring method has the advantages of high sensitivity, low disturbance and good selectivity and reappearance. The relative standard deviation is lower 1.0% and the standard adding recovery rate is within the range of 97%～102%. The method is completely suitable for the control analysis of iron-potassium-calcium in Ni-Cd battery and for the analysis of sample system.
