摘要
对石墨炉原子吸收光谱法测定原油中砷含量的方法进行了研究,考察了砷含量测定的干扰因素,确定了实验条件。此方法的测定范围为0.03μg/g～0.4μg/g,加标回收率在96%～104%之间,可满足原油中微量砷的常规检测分析要求。
The method for determination of low level arsenic in crude-oil using Graphite furnace atomic absorption photometric （GFAAS）was evaluated. The disturbances for determining low level arsenic in crude-oil were considered. The range of this method could be from 0.03μg/g-0.4μg/g. And the recovery rate covered from 96 % to 104 %. This method could meet the need of routine analysis of low level of arsenic in crude-oil.
