Abstract [en]

The use of nitrogen as plasma gas for microwave plasma atomic emission spectroscopy (MP AES) is an interesting development in analytical science since the running cost can be significantly reduced in comparison to the inductively coupled argon plasma. Here, we evaluate the performance of the Agilent 4100 MP AES instrument for the analysis of principal metals (Ca, K, Mg, and Na), lithogenic metals (Al, Fe, and Mn) and selected trace metals (As, Ba, Cd, Co, Cr, Cu, Mo, Ni, Pb, V, and Zn) in nitric acid plant digests. The digests were prepared by microwave-assisted dissolution of dry plant material from sunflower (Helianthus annuus) in concentrated nitric acid. Comparisons are made with analysis of the same solutions with ICP-MS (Agilent 7500cx) using the octopole reaction system (ORS) in the collision mode for As, Fe, and V.

The limits of detection were usually in the low μg L-1 range and all principal and lithogenic metals were successfully determined with the MP AES and provided almost identical results with the ICP-MS. The same applies for the selected trace metals except for As, Co and Mo where the concentrations were below the detection limit with the MP AES. For successful analysis we recommend that (i) only atom lines are used, (ii) ionization is minimized (e.g. addition of CsNO3) and (iii) the use of internal standards should be considered to resolve spectral interferences.

Abstract [en]

Worldwide the modern society produces vast amounts of waste materials containing strategic and valuable metals. Some of them are of substantial economic or environmental significance if controlled recovery of metals can be performed or if uncontrolled release to the environment occurs.

By cultivating Agrostis capillaris on historical sulfidic mine waste the leachate composition can be altered and its volume reduced. In combination with additives such as bark compost and water works granules the concentration of several hazardous metals decreased significantly already after eight weeks. Limited actions can therefore be used to decrease the environmental impact from such waste.

Shale in general contains considerable amounts of strategic metals. If naturally occurring microorganisms are provided with a source of nutrients, increased mobilization of strategic metals can be obtained. By using wood chips as the nutrient source the mobilization of vanadium and uranium increased significantly. Highest mobilization efficiency was observed when the carbon source was put on top of the shale.

Analysis of strategic metals is often performed by argon plasma techniques such as ICP-QMS. However, the use of argon increases the analytical costs. If isotopic information is not needed and slightly higher uncertainties can be accepted, several strategic metals can successfully be quantified by the nitrogen plasma based MP AES. The analytical cost can then be cut with more than 99%.
