摘要
采用微波方法消解汽油样品,将汽油样品置于密闭容器内,加入一定量的硝酸,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、等离子体发射光谱法同时测定汽油中锰铜铁铅磷的方法。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<2%,加标回收率为91.7%～107.6%,具有消解用试剂量少、操作简单、检测速度快,多元素同时测定,减少环境污染等优点。
A method for the determination of manganese, copper,iron,lead,phosphorus in gasoline by inductive coupled plasma-atomic emission spectrometric with microwave sample digestion has been developed. The method has realized synchronous determination of many elements in one time and no interference between the detected elements was found. The recoveries of the method for these elements are 91.7%-107.6% , and relative standard deviation （RSD,n=11 ）〈2%. compared with the commonly used single-element analytical techniques, the proposed method has the advantages of more reliable and more efficient.
