Green Synthesis of Colloidal Silver with Honey and Carob Gum
As possible applications of colloidal silver as an effective antibacterial agents, there were found lot of methods of preparation of colloidal silver with natural reducing agents, harmless for human health, which often have a positive effect on human health. The paper examined the possibility of preparation of colloidal silver by reduction of silver ions from the silver nitrate solution with honey and addition of carob gum as colloidal stabilizer. For green synthesis of colloidal silver applied honey was from chub tree from Međimurje area, and as a protective agent carob gum was used, which stops the growth of colloidal silver, extracted from the carob seeds which originate from the Dalmatia area. Silver colloidals were prepared at different pH value (6.5-8.0) and were tested for Tyndall effect by passing the laser beam and UV-Vis spectrophotometer in the range of 300-600 nm. Spectrograms were compared with colloidal silver prepared with reduction of silver ions with sodium borohydride, which applied as standard sample. Colloidal silver prepared with green synthesis has pronounced Tyndall effect and UV-Vis spectrograms show the existence of a characteristic peak of the colloid, but with different intensities and different wavelengths depending on the concentration of the applied reducing agent.
