中文摘要: 采用微波消解-电感耦合等离子体发射光谱法与石墨炉原子吸收光谱法测定了考核样明胶中的铬含量，并与石墨炉原子吸收法的测试结果进行比较，发现电感耦合等离子体发射光谱仪（inductively coupled plasma optical emission specrometry，ICP-OES）法能够更加快速、准确地对样品进行分析，具有更高的稳定性和更低的检出限，这为ICP-OES法在食品铬含量测定中的研究提供可靠的试验数据支持。

Abstract:The chromium content in the gelatin was determined by microwave digestion-inductively coupled plasma optical emission spectrometry and graphite furnace atomic absorption spectrometry，and the results were compared with those of graphite furnace atomic absorption spectrometry.It was found that inductively coupled plasma optical emission specrometry（ICP-OES）method could analyze the sample more quickly and accurately，and had higher stability and lower detection limit.The research provided reliable tested datum for the determination method of chromium content in food by ICP-OES.
