Hi, I am using sodium iodide to separate density carbon fractions of my samples. I want to recyle it for further uses. While searching I only get the process to recycle sodium polytungstate (at the stage I am not using SPT). So, I would appreciate if you give me some hands on tips for recycling NaI. Thanking you in anticipation.
Hello!
A full disclaimer, I've watched a fellow researcher show me how to do this, so I am not fully experienced with NaI recycling. I hope you at least try and I hope this works! There are actually a few ways you can do it, but I am most familiar with taking a 3:2 ratio of your NaI sample. So for example, every 30g of your NaI should be dissolved in 20mL of deionized water. Proceed to boil your solution at 130 °C for at least an hour. I've read articles in the past about salt recycling and from what I remember, many of them state that the compounds may interact during storage, but the reactions are reversible!
Best of luck!
