Abstract
In this study, an alternatifive UV-VIS spectrophotometric method for determination of magnesium was proposed. The method is based on complexation with 8-hydoxyquinoline (oxin) in sodium dodecyl sulphate (SDS) micelle medium, the absorbance of the product was recorded at 390 nm. pH of the solution, the concentration of ligand and surfactant were critical parameters, which affect the absorbance measurements, and optimised. The molar absorptivitiy coefficient is 5×102 Lmol-1cm-1, the Sandell’s sensitivity is 0,052 µgcm-2, detection limit is 0,3 mgL-1, quantification limit is 1,1 mgL-1 and linear working range is 2-8 mgL-1 at pH 12 and 390 nm. The proposed method was applied for determination of magnesium to some drug and mineral water samples, nearly good accuracy and reproducible volues were obtained percent as recovery and relative standart deviation.
