Determination of Iron in Some Selected Iron Containing Tablets Using Redox Titration

Abstract

Iron is an essential trace element, required for haemoglobin formation and the oxidative process of living tissues. A comparative study of the determination of iron in iron tablets was carried out using Redox titration on five samples of capsule containing iron. The capsules were analyzed using Redox titration on five of the samples containing iron content inform of ferrous fumarate. The weight of ferrous fumarate Fe (C 4 H 2 O 4) as well as elemental Fe 2+ in milligram per gram for each capsule containing ferrous fumarate was determined. The titration was carried out using potassium permanganate (vii) (KMNO 4) which is the oxidation agent. The results obtained indicated Chemiron contained 144±4.61 (mg/g) while the label contained 150mg/g, Astyfer contained 74.6±5.69 (mg/g) while the label contained 80mg/g, Ferrobin plus contained 246±2.36 (mg/g) while the label contain 300mg/g, Emivite super contain 102±3.64 (mg/g) while the label contain 100mg/g, and Maxiron 265±1.73 (mg/g) while the label contain 250mg/g. Base on the results for the analysis of all the sample it can be concluded that Maxiron have the highest percentage of iron which is best supplements for adult lacking high percentage of iron. However, Astyfer has the lowest amount of iron which is the best supplement for infants who require very low amount of iron supplements.
