However, by adding alkali metal or alkaline earth metal hydroxide, Water becomes alkaline and ammonium ions turn into ammonia. This ammonia can pass through the microporous polymer membrane as a gas. This permeated ammonia is reacted with a carrier liquid, and the amount of reaction is detected using a spectrophotometer or electrochemical detector.
Ammonia can be measured. The purpose of adding alkaline metal salts, which form hydroxides, to the sample water is to remove deposits from the membrane, and by adding this, ammonia permeation becomes constant, resulting in a stable response. be able to.
