ICP-AES法测定复合肥中磷、钾、锌、锰和硼

Determination of P,K,Zn,Mn and B in Compound Fertilizers by ICP-AES

用ICP－AES法同时测定了复合肥中磷、钾、锌、锰和硼，确定了仪器的工作参数，对分拆线的选择、背景扣除、酸度影响和共存元素间的干扰等进行了研究。方法的回收率为95％－104％，相对标准偏差为2.66％－554％。

A method for determination of P,K,Zn,Mn and B in compound fertilizers by ICP-AES has beenreported in this paper. The instrument parameters have been optimized. Selection of element analyti-cal line, acidity effects and interferences of coexisted elements have been studied. The recovery was95% - 104 %, the RSD was 2. 66% - 5. 54%.
