How to detect the contents of chloride and sulfate ions in liquid ammonia
Thread Content
The manufacturers who use liquid ammonia ask us to provide the levels of chloride and sulfate ions. Since our product is already of top quality, with a liquid ammonia content of over 99.9%, the levels of chloride and sulfate ions must be very low. The methods we learned earlier, such as using silver nitrate to detect chloride ions and barium chloride to detect sulfate ions, are certainly not applicable here. Please, experts, help us as soon as possible. Thank you
Using what we learned in our textbooks, experimental methods definitely won’t work. There are currently instruments on the market for detecting chloride ions and sulfate ions, so you can purchase such devices for testing. Domestically produced ones are probably not expensive either. :)
Regarding the opinion from the same floor, ion chromatography might be worth considering.
Is ion chromatography being used? I wonder if it can be detected with such a small amount? Is ICP okay? Is there an instrument like *S?
