摘　　要：进行了紫外光度法测定复合肥中硝酸铵含量的波长选择试验,不同分析室、不同紫外光度计采用单波长法和双波长法的测定对比试验,建立了用单波长紫外光度法测定氮磷复合肥中硝酸铵含量的方法。This paper introduces the tests for determination of content of ammonium nitrate in NP compound fertilizer by means of UV spectrophotometry. By comparing the results obtained by single-wavelength UV spectrophotometry and double-wavelength UV spectrophotometry in different analysis laboratory, the author makes an conclusion that the single-wavelength UV spectrophotometry is more reliable for determination of content of ammonium nitrate in NP compound fertilizer.
