Question: Methods for adding sulfate ions to water samples
Thread Content
This post was last edited by Moon Bridge Edge on 2012-3-16 09:56. There is a type of industrial wastewater with a neutral pH value. It is desired to increase the concentration of sulfate ions (SO42-) in this water sample, without changing its pH value, and while trying to avoid increasing the concentrations of anionic or cationic ions. Alternatively, any additional anionic or cationic ions can be easily removed through further treatment. It’s impossible to add sulfuric acid directly; are there any other ways? Everyone, please share some tips. Thanks.
You want to increase the sulfate concentration without raising the concentrations of cations and anions? Where did you graduate from, exactly? ;P
