Determination of calcium, copper and nickel in royal jelly / Amalina Najwa Mohamad Shauki

This experiment was done to determine the concentration of calcium, copper and nickel in Royal Jelly using Atomic Absorption Spectrometry (AAS). Two different methods were used which method 1 was carried out by using hydrochloric acid and method 2 was carried out by using hydrogen peroxide. The correlation coefficients from the calibration curve were 0.983, 0.997, and 0.998 for calcium, copper and nickel respectively. The highest concentration of calcium in Royal Jelly was sample 3 by using method 2 which was 316±0.021. The highest concentration of copper in Royal Jelly was sample 2 by using method 1 which was 0.977±0.050 and the highest concentration of nickel in Royal Jelly was sample 2 by using method 1 which was 0.039±0.003. This can be concluded that calcium has the highest concentration in Royal Jelly foliowed by copper and nickel.
