ICP-AES Determination of Mineral Elements in Five Edible Seeds after Microwave Assisted Digestion

Article Preview

Abstract:

The concentrations of 12 elements (Ca, P, K, Na, Mg, Fe, Se, Mn, Zn, Sn, Cu and Al) were determined in raw and roasted pumpkin seeds by ICP-AES following microwave-assisted acid digestion. The accuracy of the method determined by spiking experiments was very good (recoveries 95.48103.2%) and the limits of detection of elements of interest were from 0.1 up to 17.4μg g-1, the relative standard deviations were less than 3.52%. Compared with watermelon seeds, winter melon seeds, sunflower seeds and hanging melon seeds, the results showed the five kinds of roasted melon seeds are all rich in mineral elements.
