摘要
本文叙述用快速干灰法处理样品测定奶粉中金属元素的含量,并与常规的干法和湿法处理进行对比试验,用三种方法进行的回收试验和精密度试验所得结果,经统计分析表明,快干法测定的结果准确可靠,准确度、精密度以快速干灰法为最好。
Gives a brief account on the determination of metal elements content in milk powder by a rapid dry-ashing, and makes a comparison test between the normal dry process, wet process and rapid dry-ashing. The retrieval and precise tests were carried out by three processes.According to statistic analysis these results show that the rapid dry-ashing is accurate and rcliatlc. The accuracy and precision of the rapid dry-ashing are the best over others.
