| Streszczenie: | Within the framework of this work, the synthesis and study of the stability of a triple chelate iron-containing complex, iron (II) ascorbatolizinate, was carried out. For the synthesis of iron (II) ascorbatolizinate, lysine monohydrochloride, ascorbic acid, iron sulfate, and barium hydroxide were used. To study the stability of iron (II) ascorbatolizinate, a multifactorial experiment was carried out, which included three input parameters and three levels of variation. The active acidity of the medium, the mixing time, and the temperature of the solution were considered as input parameters. The output parameters were changes in the value of optical density and a change in the value of the redox potential. Within the framework of the study, the optimal configuration of iron (II) ascorbatolizinate was determined by the method of quantum chemical modeling. It has been established that the configuration in which the interaction occurs through the carboxyl group and α-amino group of lysine and through the C2 and C3 hydroxyl groups of ascorbic acid is optimal. It has been shown that iron (II) ascorbatolizinate is chemically stable at the following technological parameters: pH from 4 to 9, exposure time from 5 to 20 min, and temperature from 25 to 60 °C. |
