A number of reports prevailed in the literatures indicate that synthesis of nanoparticles by chemical approaches are eco unfriendly and expensive. Thus, there is a growing need to develop environmentally and economically friendly processes, which do not use toxic chemicals in the synthesis protocols. In this paper, the green synthesis of colloidal silver using floral honey was studied at pH values of 6, 7, 8, 9 and 10. During the synthesis, ultrapure water, floral honey solution, silver nitrate solution with a concentration of 0.001 mol dm -3 and sodium hydroxide solution with a concentration of 0,1 mol dm -3 were used. After the synthesis, the presence of colloidal silver and the concentration of silver in the solution were checked by passing a laser beam through the solution, which led to the appearance of the Tyndall effect in all samples. Characterization of the obtained silver colloid samples was carried out by UV-Vis spectrophotometry in the wavelength range from 300 to 800 nm and by FT-IR spectrometry in the wavelength range from 4000 to 650 cm -1 . The results of UV-Vis spectroscopic analysis showed the appearance of surface plasmon resonance in all samples. The absorbance intensities indicate more favorable conditions for reactions at higher pH values. FT-IR measurements were performed to identify possible biomolecules responsible for the formation and stabilization of silver nanoparticles synthesized using honey. Small differences in wave numbers and absorption band intensities were observed in the spectra of colloidal silver samples at different pH values.
