“…Several methodologies have been published for magnesium detection in different environmental samples, these includes X-ray atomic spectrometric methods, [5] electrochemical methodologies, [6] atomic absorption spectroscopic methods, [7] flame atomic absorption spectrometric methods, [8] ion-selective electrode methods, [9] derivative spectrophotometric methods, [10] high performance liquid chromatography (HPLC), [11] nuclear magnetic resonance (NMR), [12] colorimetric methods, [13] graphite furnace atomic absorption spectrometric methods [14] and fluorescence methods. [15] In addition a few methodologies have been published for the determination of magnesium in different pharmaceutical samples, for example electrochemical methodologies, [16] atomic absorption spectroscopic methods, [17,18] flame atomic absorption spectrometric methods, [19,20] ion-selective electrode methods, [21] derivative spectrophotometric methods, [10] HPLC, [22] and colorimetric methods. [23] These analytical methodologies still have some drawbacks, such as full sample consumption, requirement for complex technologies steps, the necessity for use of time-consuming and costly machinery and the need for skilled operators.…”
