P204, P507 correlation issue
Thread Content
I have recently come across nickel-cobalt separation projects, and I would like to ask about the conditions for using P204, P507, and Cyanex272, such as pH and temperature； What are the differences between P507 and Cyanex272, and what are their respective advantages and disadvantages? I welcome experts to engage in active discussions so that I can learn from them; I would be extremely grateful
Has no one come? I’ve done some research and asked some friends; the optimal pH for using P507 is 4-5, but the pH of the feed liquid should be 1-2 in order to neutralize the alkali used in saponification. I know very little about this topic, so I hope experts will kindly share their knowledge with me
A feed pH of 4-5 is sufficient; a pH of 1-2 is not necessary
If you want to understand this in more depth, you can search for PH curve diagrams of extractants online; they show the order of extraction of various metals along with the corresponding PH values
Not many people need these three types of extractants. Which company are you from, or are you in the research field?
The saponification pH will be on the high side, right? Isn’t neutralization needed?
I’m using 204, 507; by the way, I’d like to know about 272 as well
