摘要
在用AA3型连续流动分析仪测定复混肥料中氨态氮的基础上，对AA3型连续流动分析仪法和国标法测定复混肥料中氨态氮的方法进行了比较研究。结果表明，利用AA3型连续流动分析仪能够准确地测定复混肥料中的氨态氮含量，与国标法的测定结果相比无显著性差异，标准曲线相关系数达0．9999以上，平均回收率为99．32％-100．23％。
On the basis of the determination of ammoniacal nitrogen in compound fertilizers by the Type AA3 continuous flow analyzer a study is made to compare it with the national standard method. The results show that the analyzer is able to determine accurately the ammoniacal nitrogen content, and there is no significant difference from the results by using the national standard method, with the coefficient of correlation reaching over 0.999 9 and the average recover）, at 99.32% - 100.23%.
