Problems with the austenometer
Thread Content
When using an austenometer, the solution inside it needs to be replaced frequently. It seems that there are still many active ingredients in it that could be utilized, so replacing it seems like a waste. Is there any way to detect these active ingredients in the solution so that they can be reused? Is it possible to find an appropriate indicator that can indicate the active ingredient in it?

By the time the solution in the austenometer is used up, it is basically no longer effective, or its absorption capacity is poor, resulting in a mixture containing many impurities; it is difficult to recycle such solutions. Moreover, these absorption reagents are quite cheap, so it isn’t worth attempting to recycle them. There is no need for an indicator to show the active components present, because before you even manage to use up those components, the absorption efficiency of your austenometer has already declined significantly, requiring a new absorbing solution to be used.
The main use of the residue from the austenite meter is in copper smelting, as stated by the recycling manufacturers, and I believe that too. However, I am not in favor of such savings. Quality is not guaranteed! Safety and quality are always of the highest priority!
What the two people above said makes a lot of sense; upon careful consideration, it’s not worth it! Hehe! The pursuit of savings comes at a cost; sometimes the price is higher than the benefits! It’s not worth it!
When encountering such difficult-to-handle waste, it is recommended that Haiyou collect it and hand it over to the reagent suppliers. In this way, by aggregating the amounts, it becomes easier for the manufacturers to find ways to recycle it. In fact, there are many things for which, if we take action, unexpected benefits can arise.
I agree with the view from the third floor: quality comes first. It’s not advisable to sacrifice accuracy in analysis just to save a small amount of money!
From an economic perspective, there is no value in recycling it； If it is to reduce environmental pollution, recycling could be considered.
We also use an O₂ gas analyzer every day; it’s very easy to replace the absorbent solution. It’s not worth sacrificing a little accuracy just to save some time
