Why does liquid ammonia turn slightly yellow when turned into industrial ammonia water?
Thread Content
When 99% liquid ammonia is used to prepare 25% industrial ammonia solution, what is the reason for the yellowing of the night sky? The ammonia solution prepared in the tank is new; previously, it returned to normal after the second batch was prepared. What could be the reason? Is it interference from iron ions? Is there any way to get him back to normal?
Thank you; it must have been contaminated, and things returned to normal after configuring the second slot.
Water quality and the cleanliness inside the tanks all have an impact. Those that have already changed color can be treated with an activated carbon filter
Clean the tank or switch to a plastic fitting; if this occurs with an ammonia generator, it may be due to the quality of the water
Liquid ammonia may contain oil contaminants
Could you tell me what substances are causing the pollution, OP? Thank you
In previous designs, ammonia was supplied through an outlet at the top of the storage tank; this situation rarely occurred. To reduce the time required for filling, bottom feeding was adopted. As a result, after each use and during the process of refilling with ammonia, oil residues and other impurities on the inner walls were washed away, leading to this issue. Due to limited laboratory facilities, quantitative analysis cannot be performed.
