| Abstract: | It is important for the development of total water-recycle system to remove the weakly ionized species-ammonia in Space Station.The optimifation factors including applied current, ammonia concentration, flow velocity are studied through the experiment removing weakly ionized species-ammonia by EDI. A theoretical analysis of various influencing factors is also given. The results show that using EDI, ammonia ion concentration can be reduced from 208.3 mgL~(-1) to 0.072 mgL~(-1) in water. |
