| 摘要: |
| 本文报导了一个测定奶中多种元素的新方法。样品经450℃灰化后,用6当量盐酸容解残渣,然后用电感耦合等离子体光谱仪同时测定溶液中 Ca、Mg、Fe、Sr、Ba、Zn、Mn、Cu、和 Al 的含量。文中讨论了观察高度和正向功率对谱线强度的影响,并确定了仪器工作的最佳折衷条件。结果表明,该方法适用于奶中无机元素的分析。 |

| Abstract: |
| This paper reported a new method used in the determination of multi-elements in milk.After the sampies were ashed at 540℃,residues were solved with a equivalents of hydrochloric acid.And then,the contents of Ca/Mg/Fe/Sr/Ba/Zn/Mn/Cu/Al in the solusion were determined by means of the inductively coupled plasma-atomic emission spectroscopy (ICP-AES).Also,this paper discussed the effects of observed height and positive power upon the strength of spectrum lines,and determined the best trade-off working conditions of the instrument.Results indicated that this method was adaptable to the analysis of inorganic elements in milk. |
