Is the impurity gas in chlorine CO2 or O2?

This post was last edited by sunjl1981 on 2013-1-7 00:02. If it’s CO2, is it related to the addition of soda ash during saltwater purification? # hcbbs

It mainly contains oxygen, and the amount of oxygen is directly related to the electrolysis conditions.

Both gases are present, but compared to the detection of oxygen content, detecting carbon dioxide is not easy; that’s why we often talk about the oxygen content in chlorine rather than its carbon dioxide content. The amount of carbon dioxide present is mainly determined by the amount of sodium carbonate added during the purification of saltwater, as we usually add 0.3–0.5% more of it than necessary.

Oxygen is probably the main one; if there is carbon dioxide, its amount is extremely small. This is just my personal opinion

It mainly contains oxygen; for the original graphite electrodes, there is carbon dioxide.

It is mainly oxygen, with a small amount of carbon dioxide.

It contains oxygen, or a small amount of carbon monoxide

Oxygen is definitely present, but carbon dioxide is also present; when producing trichlorosilane, the use of liquid chlorine allows the carbon content in trichlorosilane to meet the required standards, whereas production using chlorine gas directly does not achieve these requirements. Therefore, chlorine should contain carbon compounds such as carbon dioxide

Agree with the view on the second floor; it mainly contains oxygen.

I think that as long as sodium hydrochloride is added to salt water, CO2 will definitely be produced at the anode. Because the potential for the evolution of CO2 is lower than that for the evolution of O2 and Cl2. Additionally, CO2 is a weak acid and can be easily displaced by HCl. I unfortunately fell into a \"trap\" while downloading materials; all my money was taken from me, and now I have nothing at all and it’s very difficult for me to get by. I hope to receive warmth from fellow sea lovers. I bow in gratitude! This post was last edited by haining on 2009-2-5 10:15.]

It depends on where the chlorine is obtained from. If it’s produced through electrolysis, then CO2 levels are generally not high, as the 21.39 valve is used to remove CO2. Check to see if this valve is open. If O2 levels are high, then it might be due to insufficient acid addition, or the salt concentration in the brine might be too low – the acceptable range is 305+-5. Also, make sure that the temperature of the tank doesn’t exceed 90 degrees for long periods, as this can cause the brine to boil: victory:

Both have them. Oxygen is produced as a by-product. Soda ash produces carbon dioxide due to the acidity at the anode, as do organic substances.

It should be the chlorine content; there is no source for carbon dioxide, and its amount in chlorine is extremely small.
