Determination of Manganese in a vitamin tablet by Atomic Absorption Abstract Iron is one of the most abundant metals on Earth and is essential for maintaining good health. Companies that sell iron vitamin tablets display the amount of iron contained in their tablets. The objective of the experiment is to analyze the iron tablets through a spectrophotometer to measure the absorbance of iron to determine if the iron tablets contain the amount displayed. The milligrams of iron displayed about a dark red iron tablet were 15 milligrams of iron. The dark red iron was analyzed and it contained 18.1 milligrams of iron, more than what the iron tablet should have. Methods The procedure for the experiment can be found in the Harris website in PDF format pages 48-49. A dark red iron tablet was used to measure the absorbance. The pill was said to contain 15 milligrams of iron so in step one of the procedure, 5.00 mL of the solution should be diluted instead of 10.00 mL. Spectrophotometer number 5 was used to measure the absorbance. Pipette
