通过原子吸收光谱法测定不同来源大豆生产的大豆原油中Cu、Fe和Zn离子的含量，及各离子在精炼过程中的变化，表明不同国家的大豆生产的大豆油金属离子含量存在差异。精炼工艺能有效降低大豆油中的金属离子含量，精炼脱胶脱酸和脱色是金属离子含量减少的重要工段，实际生产过程中可通过监控以上工段达到控制金属离子的目的。

By atomic absorption spectrometry determinationof different sourcesof soybean production of the soybeanoil,thecontentofcuprum,fertum and zinc ion and thechangesof various ion in the refining process were studied. The results showed that metal ioncontents were different in soybeanoil of soybean production in differentcountries. Refining processcould effectively reduce the metal ion content in soybeanoil,refined degumming acid and decoloring were important sectionsof reducing metal ioncontent. Monitoring the above section in the processof actual productioncould achieve the purposeofcontrolof metal ions.
