Critical Evaluating for Five Digestion Methods Using Icp MS

Abstract

and Zn and the non-metal Se are considered ''trace elements''(TE) because of their essentiality and very limited quantity in humans. Therefore, this study aims to understand the heavy metal contents in human biological materials, using different digestion methods and to recommend the most appropriate digestion method making this measurement. Three reference materials from different sources were selected to be digested by five methods to determine the contents of these trace elements by ICP-MS. The five digestion methods were nitric acid, nitric acid-hydrogen peroxide, nitric-sulfuric acid, nitric-perchloric acid and sulfuric acid methods. Analytical results indicated that the nitric acid procedure was the most efficient for recovering Br, Ca, Cd, Cr, Cu, Fe, Hg, Mn, Ni, Pb and Zn from most certified reference materials. The sulfuric acid procedure yielded the lowest recovery of Pb from the certified reference material. The nitric acid procedure was recommended as the method for digesting the human biological materials samples herein, based on recovery analysis, cost and time taken. Nitric-perchloric acid procedure was not recommended because perchloric acid is potentially hazardous during digestion and it recovers relatively little heavy metal.

Evaluation of serum ferritin and some metal elements in type 2 diabetes mellitus patients: comparative cross-sectional study

“…Both clinical methods were performed using automated chemistry analyzer ABX Pentra 400 (HORIBA Medical Diagnostics Instruments & Systems, Montpellier, France). Trace element levels were determined using wet acid digestion method 10–12. All sample containers were meticulously washed with nonionic detergents solution and rinsed triply with distilled water and dried in the oven at 80°C for 24 hours.…”

“…In addition, uranium and potassium40 which is radioisotope of its element get into the flora and are comprehensively stored in young plants 3 . In recent years, with enhanced awareness of the importance of trace elements on health, an increasing numberof reports on the level of trace elements in human biological material traditional medicines have been published 4 and their roles in traditional medicine such as India 5 , Nigeria 6 , Pakistan 7 and Morocco 8 . The levels of many elements in the living organisms are governed by metabolic processes, like active transport or excretion.…”

Analytical application of the reaction system alizarine-hydrogen peroxide in borate buffer media for the spectrophotometric kinetic determination of Ni(II)

“…Atomic absorption spectrometry (AAS) methods, like flame (FAAS) [1][2][3], electrothermal (ET AAS) [4], high resolution continuum source graphite furnace (HR-CS GF AAS) with a previous extraction from the original matrix) [5] are very interesting. Also, inductively coupled plasma (ICP) methods like ICP-MS [6,7] and ICP-OES [8,9] are in expansion. Various classes of organic reagents, especially hydrazones, have been described as spectrophotometric reagents for Ni(II) determination [10][11][12][13].…”
