Abstract:
Background: Iron deficiency in the human body decreases the hemoglobin level and so iron deficiency anemia occurs. In this case, doctors recommend
the use of medical preparations in different forms: solid or liquid.
Material and methods: In order to determine the quantity of Iron (III) in different medical preparations that contain Iron (III)-hydroxide polymaltose
complex the analysis starts with the breakdown of the complex in acidic media. At the interaction of the mineral acids with Fe (III) hydroxide polymaltose
complex during heating the brown color disappears and Fe (III) ions pass into the solution.
results: It was shown that iron forms with sulfosalicylic acid a red-violet compound in acid media that absorbs light at a wavelength of 505 nanometers.
The object of the study consists in the photometric method of the analysis of Fe in liquid forms, with the addition of sulfosalicylic acid using the standard
addition method. Due to the fact that in a basic medium Fe (II) gently oxidizes to the Fe (III), then by the photometric method with sulfosalicylic acid
it is quantitatively determined even Fe (III), as well as the summary content of Fe (II) and Fe (III) in the analyzed solution.
conclusions: A new method of iron analysis was developed. It can be recommended to determine the iron in liquid medical preparations.
