Absorption using NaOH solution to produce sodium hypochlorite; 2. Using ferrous chloride solution along with scrap iron to generate ferric chloride, which is then reduced back to ferrous chloride by the iron scraps. Which of these two methods is more efficient and stable? Please give me some advice, thank you. # + +
It’s a good suggestion; we thought the same thing. But theory is one thing – the amount there is too small, and the response time is slow. Chlorine needs to be released. Hey, don’t risk your life just to save a little money; it’s not worth it
It should be that absorption is faster using NaOH solution, and by-products are also generated.
Friends on the 2nd floor, under what circumstances do you absorb chlorine gas? Let’s exchange ideas

It’s definitely sodium hydroxide that has a better absorption effect, as sodium hydroxide participates in reactions with molecules in solution; these are essentially strong acid-base reactions that occur very rapidly. Iron filings, on the other hand, are larger than molecules, so there is a reaction process that takes place from the outside to the inside of the iron filings. Just as iron rusts over time, it takes a process. That is far inferior to the reaction speed in a solution.
Theoretically, the approach of using ferrous chloride to absorb chlorine is feasible, but it has been found that ferrous chloride solutions with low concentrations do not absorb chlorine effectively (a 10 g/l solution – experiments were conducted on it yesterday); experiments with higher concentrations have not yet been carried out.
I’m really impressed by these amateurs upstairs. It is entirely feasible to use ferrous chloride to absorb chlorine; the cost is several times lower than that of using alkalis, and the resulting ferric chloride can be sold. Those interested can contact myben@126.com
