Determination of palladium, platinum and rhodium in used automobile catalysts and active pharmaceutical ingredients using high-resolution continuum source graphite furnace atomic absorption spectrometry and direct solid sample analysis

Quo vadishigh-resolution continuum source atomic/molecular absorption spectrometry?

“…From a methodological point of view, practically all that was discussed in the review mentioned before 21 holds true. The technique has shown potential to analyze very different types of materials, from some that could be considered as relatively easy for graphite furnace decomposition, such as polymers, biological materials or pharmaceuticals, to others that are quite refractory and, also, very difficult to bring into solution quantitatively, such as automobile catalysts, 24 fertilizers, 25 high-purity silicon 26 or silicon carbide, 27 in addition to many types of environmental samples.…”

Atomic spectrometry update. Review of advances in the analysis of metals, chemicals and functional materials

“…The determination of PGM at low levels (mg g À1 to ng g À1 ) is an analytical challenge because of the difficulty in bringing them in solution and occurrence of interferences when using spectroscopic techniques for analysis. Resano et al 83 investigated the potential of high-resolution continuum source (CS)-GFAAS for direct determination of Pd, Pt and Rh in two different types of samples: used automobile catalysts and APIs. The authors observed that the matrix in the API, consisting of organic compounds, was removed efficiently during the pyrolysis step.…”

Key Challenges and Opportunities for an Effective Supply Chain System in the Catalyst Recycling Market–A Case Study of Poland

“…Raising public awareness about air pollution and stricter standards and regulations [1] has a significant impact on industry, transport and energy production. The use of catalytic converters [2] provides one of the solutions to the problem of minimising the dispersion of toxic compounds and lowering the amount of exhaust fumes emitted to the atmosphere during the combustion of fuels in passenger cars, trucks and buses, and many other types of machinery [3]. As most catalytic converters contain a combination of the three metals, Pt, Pd and Rh [4,5], the manufacture of catalysts for automobiles is the largest sector of demand for and consumption of PGMs (platinum group metals) [6][7][8].…”
