Analytical chemistry of Pt article 2

[Lou]

Any of you using stannous chloride will find this article useful!

Again, a few hundred dollars can get you all you need for quantitative analysis of PGMs.



PS--this is a must read for spectrophotometry:

I like these methods because they use common reagents for the most part. Articles that I read in the past used expensive and difficult to obtain indicators.

This is plenty accurate for QC work.

I know how to do a spectrophotometry analysis. I learned it at school last session in Analytical Chemistry II.

Thanks for the document Lou.

Hi Lou,

When I click on the attachement I get the following message:

The selected attachment does not exist anymore.

Would it be possible to bring this attachment back to life again?

And here it is as a pdf.

The Tin-Tellurium co precipitation method if extremely high level of accuracy is required. it is unlikely that anyone will share the method details due to commercial sensitivity.

Actually at an IPMI conference last fall In Golden, CO BASF did just that.

I will post link when I get back from vacation

I hope this file is useful for those who want to analyze PGM minerals
