| Abstract: | The method of water sample preliminary treatment has been improved for determining the NH3-N in water sample by Nash reagent colorimeter.As is proved in the experiment,the two improved methods can reduce blank testing value of the whole process.They prove to be precise and can be worth being popularized. |
