摘　　要：用微波消解/电感耦合等离子体发射光谱法(ICP-OES)同时测定了三元复合肥中的铜、铁、锌、镍、锰、钼6种微量元素。结果表明,该法具有简便、快速、结果可靠、检出限低、良好的精密度、精确度、高回收率以及能够同时测量多种元素的优点;通过对比实验测量得到了有效态微量元素的浓度和微量元素的总量,结果显示大部分微量元素是以有效态形式存在于复合肥中。因此,该法可以作测量复合肥类产品中的微量元素的一种参考使用方法。Using microwave digestion and inductively coupled plasma optical emission （ICP - OES） six trace elements copper, ferrum, zinc, nickel, manganese, molybdenum contains in NPK compound -fertilizers were determined simultaneously. It＇s a handy, rapid and reliable method that have a low detection limit, high accurate and precise, high recoveries of standard addition. By comparing two processing methods to test effective and total content of trace elements in NPK compound - fertilizers. The results show that main body of fertilizer can be absorbed by plant. So this method should popularize to test trace elements of other chemical fertilizer.
