渣油中铁含量的测定分析方法的建立——微波灰化-电感耦合等离子发射光谱法

Establishment determination and analysis of iron content in residue--Microwave ashing inductively coupled plasma atomic emission spectrometry

为了节省样品处理时间,避免传统电炉灰分方式耗费的人力及带来的误差因素,提高结果准确性,采用微波灰化技术对渣油样品进行灰化处理。加酸溶解成水溶液后用电感耦合等离子发射光谱(ICP)进行铁含量测定,相对标准偏差为3.6%,加标回收率在92%~102%。

In order to save sample processing time,avoid manpower and error factors caused by traditional electric furnace ash method,and improve the accuracy of results,Microwave Ashing technology was used to ash residue samples.The relative standard deviation was 3.6%,and the recovery was 92%~102%.
