Determination of Magnesium in whole Blood and Serum of Ischemic Heart Disease(IHD) Patients by Flame Atomic Absorption Spectrometry

摘要

Flame atomic absorption spectrometric determination of magnesium in whole blood and serum of ischemic heart disease patients and control with different ages and sex was proposed. The limiting interfering phosphate/magnesium ratio have been estimates.2%w/v AlCl3.6H2O was found to be very influential in removing phosphate interference effects. The detection limit was 0.065 μg/mL .Magnesium added to blood and serum sample, and carried through this method may be recovered completely (96% - 100%) recovery percentage. The suggested method is simple, fast and selective. The statistical analysis of magnesium levels in blood and serum showed that blood and serum magnesium levels in patients were lower than magnesium contents of control group. Magnesium levels in blood and serum of males were significantly lower than females and the magnesium levels were age independent. These findings indicates that there was an association between blood and serum magnesium deficiency which can induce an entire array of path physiological phenomena known to be important in ischemic heart disease.
