Determination of minerals in commercial honeys using atomic absorption spectrometry and inductively couple plasma-optical emission spectrometry / Nurul'ain Arrifin

This study was conducted to determine the amount of minerals in the commercial honeys which were Kehdut, Tualang and black seed honey. Honey was chosen as subject because people ate it for health. The instruments used for the analysis were Atomic Absorption Spectrometry, AAS and Inductively Couple Plasma-Optical Emission Spectrometry, ICP-OES while the minerals chosen were iron (Fe), magnesium (Mg), lead (Pb), calcium (Ca), and copper (Cu). The sample preparation used for the project was wet digestion. The concentration of the minerals in the sample were determined and compared. In AAS analysis, Kehdut honey gave the highest amount of iron while in ICP, black seed honey has the highest amount of iron. Of all the three honeys, black seed honey contains the highest amount of minerals compared to the other two honeys. For AAS result, the amount of magnesium in black seed honey was 15.2 mg/L and the amount of iron was 6108 mg/L. For ICP-OES, the magnesium in black seed honey was 7.8 mg/L while iron was 14.75 mg/L.
