| 中文摘要: |
| 采用微波消解-电感耦合等离子体发射光谱法，通过对微波消解体系和消解程序参数等的优化，筛选合适的元素分析谱线，实现了天然胶乳中铜、锰、镁含量的同时快速测定。结果表明，该方法铜、锰、镁标准溶液质量浓度在0～10.00 mg·L-1范围内与特征谱线强度具有良好的线性关系（相关因数≥0.999 7），3种元素含量测试的相对标准偏差为1.68%～2.61%，检出限为0.013～0.035 mg·kg-1，加标回收率为99.12%～102.83%，完全满足相关检测的要求。 |

| By using microwave digestion and inductively coupled plasma optical emission spectrometry（ICP-OES），optimizing the conditions of microwave digestion system and digestion program parameters，and screening suitable element analysis spectral lines，the simultaneous and rapid determination of copper，manganese and magnesium contents in natural rubber latex was achieved.The results showed that，the mass concentrations of copper，manganese and magnesium standard solutions in this method had a good linear relationship with the intensities of characteristic spectral lines in the range of 0～10.00 mg·L-1，
the correlation factor was above 0.999 7.The relative standard deviations of the three elements were 1.68%～2.61%，the limits of detection were 0.013～0.035 mg·kg-1，and the recovery rates were 99.12%～102.83%，which could meet the relevant detection requirements. |
