Seeking help with the analysis of metal cobalt
Thread Content
I conducted some experiments to produce electrolytic cobalt; I’m looking for someone in this forum who can conduct tests to help determine the purity of the cobalt. Thank you very much!
Are there any friends in this area? ?
The basic content of cobalt with electrolytic purity should exceed 99.9%; it is no longer necessary to test the purity, and it is more appropriate to directly examine the level of impurities present. If it are ordinary impurities, they might be iron, nickel, copper, sulfur, arsenic, etc.; impurity testing can be used to determine the purity by subtraction.
Let’s keep it simple first! After all, it was my own experiment; I’ll check the purity first and then think about ways to improve it.
Qugd is right; the original poster didn’t understand. In fact, a substance with such a high concentration is no longer suitable for direct analysis as its main component, as the main content is usually determined by subtracting the total amount of impurities from 100%.
This principle is of course understood; what’s needed now is to find out where one can get help with the testing! Thank you!
Beikang University should be able to do it; the price might be a bit higher.
To measure the impurity content, and then subtract that value, ICP-AES can be used for this purpose! :):)
I don’t know how to get in touch! Thank you!
