A simple and high sensitive spectrophotometric method for ultra trace determination of ruthenium with its catalytic effect on the oxidation of pyronin B by periodate.
Rezaei B, Majidi N. Rezaei B, et al. Spectrochim Acta A Mol Biomol Spectrosc. 2007 Apr;66(4-5):869-73. doi: 10.1016/j.saa.2006.05.002. Epub 2006 May 10. Spectrochim Acta A Mol Biomol Spectrosc. 2007. PMID: 16872868
The described method is able to quantify ruthenium in the range of 0.1-100 ng ml-1 (r=0.9973), with a detection limit (S/N=3) of 0.036 ng ml-1. Under optimum conditions, this procedure has been successfully applied to determine the trace levels of ruthenium in the environm …
