| 摘 要： | 用ICP光谱法(ICP-AES法)测定复混肥中的钾和有效磷元素含量,并与GB/8574-1988四苯基硼酸钾重量法、GB/8573-1999磷钼酸喹啉重量法进行比较.结果分析得出,钾和有效磷的精密度分别为0.12%和0.11%,3种方法的分析结果相互吻合,ICP-AES法可以用于监测肥料、土壤和农产品中钾和有效磷的含量,提高农业生产质量,保障食品安全.

| Abstract: | At present,potassium tetraphenylborate gravimetric method is used to determine potassium in GB/T8574-98 and quinoline phosphomolybdate gravimetric method is used to determine available phosphorus in GB/T8573-1999.In this paper,it's determined simply and quickly by ICP-AES with the same pre-treatment as gravimetric method.The result is accorded.It's possible with ICP-AES method to determine potassium and available phosphorus content for compound fertilizers. |
