| Abstract: | It is discussed the existing problems of determining micro-ammonia by Nashi reagent colorimetry in the determination of micro-ammonia, it is given the path to lower the method's detection limit through reducing the volume of absorbing liquid and adding the sampling volume, and the problem of the overhigh detection limit in the determination of micro-ammonia is solved. |
