Abstract

Background: Silver nanoparticles have received a lot of attention in research over the past few years because they are part of the development of nanotechnology. Synthesis of silver nanoparticles is carried out using various methods, namely conventional heating and microwave radiation using glucose as a reducing agent. Objective: The aim of this research is to determine whether conventional heating methods and microwave radiation can produce different weights and produce silver nanoparticles with appropriate characteristics. Method: This research method includes the synthesis of silver nanoparticles using conventional heating methods and microwave radiation, and characterization of silver nanoparticles which includes analysis of maximum wavelength, functional groups, particle size and nanoparticle morphology. Results: The results of this research show that the synthesis of silver nanoparticles using conventional methods and microwave radiation produces different weights at each temperature and power variation whit the highest weights being 0.0050 g (temperature 60oC) and 0.0067 g (power 180W). The maximum characteristic wavelength for AgNP 60oC is at 371 nm and AgNP 180W is at 394 nm. Characterization of functional groups on AgNP 60oC and AgNP 180W showed the presence of O-H hydroxyl bonds (3626,17 cm-1 and 3392,79 cm-1); C-H aldehyde (2924,09 cm-1 and 2958,80 cm-1); C=O carbonyl (1631,78 cm-1 and 1602,85 cm-1); and O-H alcohol (1016,49 cm-1 and 1068,56 cm-1). Characterization of particle sizes for AgNP 60oC and AgNP 180W, namely 2814 nm and 175 nm. Morphological characterization of nanoparticles shows the morphology of particles form clusters, and there is agglomeration in the distribution of AgNP particles. Conclusion: Synthesis of silver nanoparticles using conventional heating methods and microwave radiation produces different weights at each temperature and power variation, and produces characterization values that do not meet the requirements fo the size of silver nanoparticles at 1-100 nm.
