Determination of low concentrations of inorganic and organo-metallic compounds present in steel products

Ziel

Ecolabels and environmental problems confront laboratories with the determination of elements such as Sn, Cd, Hg, Zn, Pb, Ni, Cr, As, present in low concentrations. In addition to the analysis of the total concentration of such elements, laboratories are frequently requested to specify the fraction of these elements present as organometallic compounds. The study of tribological processes (formation, etc.) also requires more and more speciation of the inorganic and organometallic compounds of certain elements. This research aims at defining a "global index for the organometallic composition". Using HR-ICPMS equipped specifically for elemental analysis of organic solvents, and gas chromatography coupled with Mass Spectrometry, OCAS and CRM will study extraction and separation methods, which allow, in solutions with different polarity, the speciation of the "inorganic and organometallic" fraction of the element in question.

The method will be applied to and the analytical performance defined for: 1) The characterisation of organometallic residues present on steel after friction tests and laboratory scale deep drawing operations (the reactivity of several additives based on zinc, phosphate, added in particular to protective oils, will be examined; 2) The analysis of inorganic and organometallic residues of heavy metals on non-oiled steel sheet for the packaging industry. One of the objectives of this research is to assess the potentialities of analytical tools such as LR-ICPMS, ETAA and ICPOES to determine such an index.
