测定煤样中金属元素的原子吸收法

Atomic Absorption Method of Determining Metal Elements in Coal Samples

近年来,煤中元素在环境中的迁移和分布受到了人们的重视。原子吸收法是定量煤样中微量元素的通用方法。煤样的灰化和样品溶液的制备是该法的关键环节,而且,方法是多种多样的,应根据具体情况选用。

People have attached great imporlance to the motion and disposition of elements in coal in the environment in recent years. Atomic absorption method is one used commonly indetercoal in mining quantitative metal elements in coal, the coal ashing and preparation of sample solution are a key link to the analyasis method and there are various kinds of methods. So we have to make our choice in the lighe of actual conditions.
