Abstract
The benefits of ICP-OES analysis (radial observation) for humic products are evaluated in this paper; the proposed method allows one to quantify up to 24 elements (As, Al, B, Ba, Ca, Cd, Co, Cr, Cu, Fe, K, Mg, Mn, Mo, Na, Ni, P, Pb, S, Si, Sr, Ti, V, and Zn). This list will make it possible to determine the effectiveness of such preparations for soil nutrition as well as help to avoid danger if the amount of toxic impurities in them goes beyond their maximum permissible concentrations. In the absence of certified reference materials for the elements analyzed, the accuracy of determining the macro component composition is confirmed by comparing the results of an independent gravimetric experiment for the objects under study’s ash content with the calculated data obtained by processing the results of ICP-OES analysis. Systematic errors in the determination of minor and micro components are minimized by using the method of standard additions to avoid matrix effects as well as using six parallel measurements on samples prepared independently of each other. The accuracy of the procedure is also assessed by using model solutions with similar micro impurities’ mineral composition of humic products using Student’s t-test. The results obtained for the isolated fraction of humic acids are compared with the literature data.
