Rhodium complexes in water at the presence of sulfate. How can i determine the complexes experimentally?
I think, Spectrophotometric determination is the simplest one. Please read the papers mentioned below:
1. Orville et al. (1971). Spectrophotometric determination of rhodium with nitriso R. Formula for the Rh (III)- nitroso R complex. Analytical Chemistry 43, 146-148.
2. Shelar et al. (2015). Extraction spectrophotometric determination of rhodium (III) with o-methylphenyl urea. Journal of Saudi Chemical Society 19, 616-627.
Hi Tarafdar
thank you for the response and articles. However I am more interested in solution chemistry of rhodium. what type of complexes are formed ( cationic, acionic, ion pairing etc) depending on the pH, temperature etc. those articles seem to related to detection and extraction of trivalent rhodium rather than analyzing the formed complexes.
