摘要
建立了塑料管中氧化-气相分子吸收光谱测定水中氨氮的方法，消除了玻璃容器中杂质的干扰。方法空白值低，检出限为0．006mg／L，测定实际水样的精密度≤3.0％，加标回收率为98.4％～104％，与次溴酸盐氧化-分光光度法作比对，结果基本一致。
The oxidize-gas phase molecular absorption spectrum with plastic tube was established for determination of ammonia nitrogen in water to eliminate impurity disturbance of glass vessels. The blank value of the method was low, the limit of detection 0. 006 mg/L, RSD of practical water sample ≤3.0% , the recoveries 98.4% - 104%. The results of this method equal to that of hypobromite oxidation-spectrophotometric method.
