- 摘要:
- 将大豆样品置于密闭容器内，加入一定量的硝酸和过氧化氢，放在微波消解系统内进行消解。建立了用微波消解，电感耦合等离子体发射光谱法同时测定大豆中的钙、钾、镁、磷、铁、锌、铅、镉、砷、汞、铬、铜、锰、锡的方法。研究结果显示：该法测定精度高，各元素的相对标准偏差(RSD,n=11)均小于2.0％，加标回收率为93.4%～109.1%，具有消解所用试剂量少、操作简单、检测速度快、多元素同时测定和减少环境污染等优点。
- Abstract:
- The soybean samples were dissolved by microwave digestion using nitric acid-hydrogen peroxide.After dilution,the calcium,potassium,magnesium,phosphorus,iron,zinc,stannum,lead,cadmium,arsenic,mercury,chromium,copper,manganese, and stannumin soybean were determined by inductive coupled plasma-atomic emission spectrometry(ICP-AES).The determination results were compared with those obtained by national standard method.It was found that the analytical results were consistent with those obtained by national standard method,the repeatability was good.The recoveries of the method for these elements were 93.4%-109.1%，and relative standard deviation(RSD,n=11)were less than 2.0%.Compared with the commonly used single-element analytical techniques,the proposed method proved to be more reliable and efficient.
