Spectroscopic, thermal analysis and bioactivity study of new ferrous citrate based materials prepared by Sol–Gel method
The aim of this work is the development of a system able to release ferrous
ions in a controlled manner. An interesting alternative to a systemic therapy
can be the use of controlled drug release for medical applications. Starting
from iron powder and citric acid, ferrous citrate (Fe(II)C) is synthesized by a
redox reaction between these two. The confirmation that only Fe(II)C is
obtained by redox reaction is shown from Fourier transform infrared
spectroscopy (FTIR), 1,10-phenanthroline and sodium thiocyanate
