Achieved aim(s) of the project

The research network was looking for a sustainable, simple and sensitive method to detect hazardous elements (Co, Ni, Cr) based on flame atomic absorption spectroscopy (AAS) in food matrices that were in contact with thermally sprayed coating solutions. These are used for wear protection of machines in food technology. To overcome the low sensitivity of AAS, the food matrices are concentrated using a high vacuum technique. The reliability of the analytical method is investigated in comparison with other methods. This is done by comparing flame AAS with graphite furnace AAS, inductively coupled plasma with optical emission detection (ICP-OES) and total reflection X-ray fluorescence method.

Main activities of the project

1) Preparation of coated specimen by thermal spraying coating for further trace element detection experiments in food matrices. Venue: Fraunhofer-Institut für Keramische Technologien und Systeme IKTS, Germany.

2) Research developing analytical solutions to get the highest sensitivity for the flame AAS when concentrating contaminated food matrices. Venue: Kaunas University of Technology, Lithuania.

3) Validation of the novel sensitivity solution for the flame AAS by other reliable trace element measurement techniques, such as graphite furnace AAS, ICP-OES and TXRF. Venue: University of Latvia, Latvia.

4) Research project results dissemination: booklets, posters and international online workshop. Venue: Kaunas University of Technology, Lithuania.
