Determination of Selanium in Food by Atomic Absorption spectropometer with Modifier

采用以镍作基体改进剂的原子吸收法测定食品中微量硒，可提高样品处理的灰化程度，降低背景干扰。该方法灵敏、准确。

Nickel(Ni)as a modifier was used in atomic absorption analysis food sampleswhich can be ashed at higber temperture. The background noise was reduced.The accuracy and sensitivity of selenium detection improved respectively.
