Which of these two testing method is more accurate, advanced and appropriate? Also, I have a spent catalyst that contains 1% platinum, can the purity increase after pre-treatment and refining?

XRF experts will surely jump in. Here is my experience on base metals assaying https://www.911metallurgist.com/blog/compare-x-ray-xrf-to-laboratory-measurement-reliability

Do you know about refining? Is possible to increase the purity of a low platinum concentrate or catalyst after refining?

I have no idea Vincent.

Thanks David for a very illuminating presentation. As you said "Get an XRF and start producing.

Hi Vincent,

I hate to be the guy that says it, but it depends. Both have a long history, and there is plenty of literature out there for both. The question is what are you trying to accomplish? Factors such as matrix, presence of interfering elements, concentration and needed precision & detection limits all need to be discussed.

In many cases, near real-time XRF is complimentary to lab based ICP MS and ICP OES. XRF can save costs on the bulk of the testing work, while confirmatory samples could be sent to the lab for verification. There are several high profile commercial labs that do use field portable, energy dispersive XRF (not to be confused with wavelength dispersive XRF), but in my opinion the value of XRF is in getting quick multi-element results on-site, that has the potential to be accurate when used appropriately.

Kind Regards,

Chris

Yes I will provide you, how to concentrate Platinum from catalyst waste.
