Multielemental fast analysis of vegetation samples by wavelength dispersive X-ray fluorescence spectrometry: Possibilities and drawbacks

摘要: Abstract X-ray fluorescence spectroscopy (XRF) is universally recognized as a non-destructive method for rapid and sequential, or simultaneous analysis of elemental composition material. The use this technique the direct determination chemical elements in plant matrices has increased over last few years. In present study, wavelength dispersive (WDXRF) quantitative some major (Na, Mg, Al, P, S, K, Ca), trace (Mn, Fe, Co, Zn, As) non-essential (Sr, Pb) vegetation specimens been developed. uses quick easy sample preparation procedure since only drying, pulverizing pressing samples are necessary. calibration was established by employing four reference materials several synthetic cellulose calibrators spiked with appropriate amounts analytes. Matrix effects were corrected influence coefficients on basis computerized routine program linked to equipment. Trueness experimental checked using standard material GBW07602 “Bush branches leaves”. general, good agreement achieved between certified values measured ones recoveries ranging from 94% 107%. Moreover, quality parameters, including repeatability reproducibility developed method, also evaluated. On whole, results obtained, WDXRF proposed prove be effective tool environmental investigation control processes specimens.
