将电解锰废渣、废液经硝酸、氢氟酸、高氯酸处理后，利用火焰原子吸收光谱法（ Ｆ Ａ Ａ Ｓ） 测定其中的锰，加标回收率在９４８ ％ ～１０２５ ％ ，相对标准偏差在３１ ％ ～８６ ％ ，倍比实验亦相吻合。该法简便、快速、准确，为环境治理和改进工艺条件提供了一定的依据。 The manganese waste and waste liquid were treated with nitric acid, hydrofluoric acid and perchloric acid, and then the manganese was determined by flame atomic absorption spectrometry (F A A S) with recovery of 948% -1025 %, The relative standard deviation of 3  1% ~ 8  6%, times the experiment is also consistent. The method is simple, rapid and accurate and provides a basis for environmental management and improvement of process conditions.
