测定氨标样的两种方法比较

Compared with the Two Methods which Determin Ammonia

采用测定水中氨的方法与采用测定空气中氨的方法进行比较,分别用两种测定氨的方法对标样进行测定,得出用水中测定氨的方法测定“空气中的氨”标样比用空气中氨的方法更加简单、方便,结果较好。用两种方法分别对环境样品进行测定,测定结果基本一致,进一步验证了测定水中氨的方法可以用于“空气中的氨”测定。

Compared with the two methods which determine ammonia in water and in air,use the two method to carry on the determination separately to the specimensample. It shows that it is quicker and better to use the water method to determine the ammonia in air , and the outcomes are nearly the same. We can conclude that the water method is also useful to the determination ammonia in air.
