Abstract: The development of ICP-AES came about due to the need for a fast multielement soil analysis. However, interferences do occur when there is a high concentration of any individual element in the soil.The trace elements Cu, Zn, Mo, V, and Mn were determined by the ICP-AES method in a soil and interferences of macroelements Al, Ca, Fe, Mg, Na, K were studied. The limits of detection for trace elements were statistically calculated. The decomposition procedure for the soil samples was performed by popular microwave oven GEM. Modelled standard solution with matrix elements was used to obtain the calibration curve. Results were compared with the certified values of elements in certified reference material SO-2.
