Download or read book The Analysis of High purity Noble Metals and Their Salts by ICP MS written by and published by . This book was released on 1994 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ongoing work is being carried out at Mintek to establish methods for the determination of trace levels of impurities in high-purity noble metals and their salts. The sample-preparation methods are outlined, and the optimum instrumental parameters that were established are tabulated. Spectral interferences arising from the presence of a matrix element at high concentration levels, including abundance sensitivity overlap and the formation of noble metal oxides, are discussed. Accuracy was established by the comparison of the results with those obtained by a DC-arc method, and by spike recovery tests. The precision of measurement was found to vary from 0.72 to 49% relative standard deviation for concentrations of between 15 and 0.5 ug/g, respectively.

Book excerpt: The platinum industry, from mining through to the final refining of the individual platinum-group metals (PGM) plus gold (the noble metals), places great demands upon the skills and ingenuity of the analytical chemist. Samples containing concentrations of the noble metals ranging from lower than parts per million through to 100 per cent must be treated, and analyses for the individual six PGM and gold are required frequently. The development of the inductively coupled plasma (ICP) as the source of excitation in optical emission spectroscopy (OES) has provided a very powerful tool for the analytical chemist. The ICP-OES technique is capable of covering a wide analytical range and, in addition, enables simultaneous multi-element analysis to be carried out. These attributes make the technique particularly attractive to the platinum industry, and suitable instrumentation has been installed in several laboratories attached to mines and refineries. For normal ICP-OES analysis, a solution is sprayed into the plasma and, therefore, solid samples have to be dissolved first. This paper describes work undertaken by Mintek on a preconcentration technique in which solids (ion-exchange resin) are sprayed directly into the plasma. The results obtained are encouraging, and further applications could be explored, e.g. the determination of low levels of the noble metals in effluents. Further work needs to be done so that iridium can be included in the analytical scheme and, since most ICP-OES systems sold all use argon low-power plasma, the feasibility of the spraying of solids into these systems needs to be examined if the technique is to find wide acceptance in industry. Another requirement for its industrial acceptance is the commercial availability of the Monivex resin.
