Determination of different trace and essential element in lemon grass samples by x-ray fluorescence spectroscopy technique

The quantitative determination of essential and trace elements via advanced X-ray fluorescence (XRF) Spectroscopic technique, in this response three different lemon grass samples were collected from different fields, among the analysed sample the highest amount of potassium (K) 53.40%, calcium (Ca) 26.19%, and silicon (Si) 10.01% were determined, while the second highest amount of sodium (Na) and magnesium (Mg) were found 2.57% and 2.05% respectively, the remaining were at below 2%. The standard deviations of samples are below than 5%. The validity and accuracy of the optimized procedure was checked by analysis of the certified reference materials (CRM)/literature values by XRF technique.
