Abstract :In this study, Al, B ,Cd, Co, Cr, Cu, Fe, Mn, Mo, Ni, Pb and Sn concentrations in henna samples sold in Turkey were determined by Microwave Induced Plasma Optical Emission Spectrometry. It is a relatively new technique, which uses a 2.45 GHz microwave magnetic field and nitrogen gas to sustain the plasma. With this technique, there is no requirement for flammable and toxic gases and their gas-cylinders. For the determination, e ach henna sample weighed approximately 0.1 g and underwent microwave-assisted digestion using 10 mL of HNO 3 +H 2 O 2 insert ignore into journalissuearticles values(3:1); mixture. In order to test the method’s accuracy, analytes were determined in bush branches and the leaves CRM. Finally, the elemental concentrations were determined in 18 different henna samples sold in Turkey by using optimized parameters.
