摘要
建立微波消解-电感耦合等离子发射光谱测定鸡肉中Ca、Fe、Zn、Se、Ni、Mn、Cu、Pb、As九种元素的方法。测定结果表明,此方法的检出限为0.0004～0.0069mg/L,相对标准偏差(n=3)为0.72%～4.10%,回收率为80.0%～107.1%。同时研究微波消解试剂的种类和加入量、微波消解升温程序对测定结果的影响;并且将微波消解与干灰化法、湿法消解进行比较,结果显示,经微波消解后,测得多种元素的值显著性高于干法灰化、湿法消解(P<0.05)。
A method was established to determine calcium, ferrum, zinc, selenium, nickel, manganese, copper, lead and arsenic in chicken using microwave digestion followed by inductively coupled plasma-atomic emission spectrometry （ICP- AES）. The limit of detection of this method was 0.4-6.9 ng/mL, and the precision （RSD） for three replicate determinations ranged from 0.72% to 4.10%. Average recoveries of 9 elements in chicken reference material and commercial chicken varied from 80.0% and 107.1%. The effects of digestion agent type and dosage and programmed heating on results of determination were investigated. Significantly higher results of determination were obtained with microwave digestion when compared with dry ashing and wet digestion （P〈0.05）.
