abstract:
The aim of this study was to compare two methods of mineralisation of rapeseed cake. Total concentration of macro- and microelements in obtained solutions was determined. The samples were mineralised by the "dry" method in a muffle furnace at a temperature of 450oC and by the "wet" method, in a mixture of 2:1 HNO3: H2O2 at 60oC. The concentration of 13 elements was determined by ICP-AES. The study showed significant differences in analysed elements concentration, depending on the method of preparation of the samples of biological material.
