The Elemental Composition of Cod and Salmon Bones Derived Powder Using SEM-EDX and ICP-OES
2014
The study aimed at comparison of the results concerning elemental composition of cod and salmon fishbone powders determined using two methods, i.e. scanning electron microscopy with an energy dispersive X-ray analytical system (SEM-EDX) and inductively coupled plasma—optical emission spectroscopy (ICP-OES). The research material were fishbone powders of marine fish: cod (Gadus morhua) from Baltic Sea and salmon (Salmo salar) from Atlantic Ocean obtained using the method of chemical extraction. The analysis included main mineral elements: calcium, magnesium, sodium, phosphorus. The results obtained from SEM-EDX appeared to be compliant with the results obtained based on ICP-OES analysis. It was demonstrated that combination of two advanced techniques for fishbone powders characterization is essential for suitable analysis of its quality as well as quantity, especially for subsequent determination of supplements composition. It may be concluded that SEM-EDX method may be successfully used for preliminary analysis of macroelements content in biological material.
