| A method for the determination of Al, Cu, Fe, Mg, Pd, Ni, Pb, Pt, Zn in tris(triphenylphosphine) rhodium(I) chloride by ICP-AES was developed. The samples were digestion by HNO3 and HClO4, then dissolved with HCl+HNO3. The matrix effects come from Rh to Fe, Ni, Pb, Pt, Zn were eliminated by background point correction. The determination range is 0.001%~0.1%. The recoveries and RSD were 93.25%~117.0% and 0.18%~15.41%, respectively. Comparing with DC arc emission spectrometry, the method is more accurate and precise, less comsumption of high purity rhodium and easy to operate. |
