摘　　要：试验采用微波消解进行样品处理,再用等离子体原子发射光谱法对饲料中的磷和硫进行同时测定。磷和硫测定的精密度分别为1.07%~2.62%和1.70%~3.35%,加标回收率分别为99.2%~100.8%和97.3%~101.6%;样品测定结果同国家标准方法一致,对相关国家标准物质的测定结果与标准值相吻合。ABSTRACT：After the microwave digestion pretreatment, we determined the tJhosphol us and sull？imr ~＇ontcut m tc,＇d 1~3 t,la~,m~： atomic emission spectrometry.
