Gold Ion Concentration

+++

I am an undergraduate electrical engineering student at Michigan Technological University. My senior design project involves the measurement of gold ion concentration in a solution containing many unknowns. Our project is an attempt to automate the process and provide real-time results. We have looked at AAS, but would like to try another option, one that would be less time-consuming to set up. Would anyone know where to look to find which analytical methods (particularly UV-VIS Spectrophotometry) would provide the measurement we are searching for? Our searches in the library haven't proven fruitful in searching for any information about gold ions.

Grab a chemistry buddy and go to Hach.com they have lots of elementry to some sophisticated analysis for many elements. Then, go to the internet and try plating solution analysis or "gold analysis" . you should get hundreds of citations from the more specific search and hundreds of thousands on the generic search.

Have you considered XRF?
