| 摘 要： | 用原子吸收空气－－乙炔炎焰法测定锰时，硅会对其产生严重干扰，若等量加入２５ｍｇ／Ｌ钡或１００ｍｇ／Ｌ镧则足以消除这一干扰作用，尤其是加入后者，可获得较真实的测值。

| Abstract: | When
determining Manganese by atomic absorption,silicon will exert heavy influence.By adding
equivalent Ba of 25mg/l or Lanthanum of 100mg/l,the interference will be eliminated.By adding the
Lanthanum,the precise determination value can be obtained. |
