Synthesis of Silver Nanoparticles (NPAg) using Andaliman (Zanthoxylum acanthopodium DC.) Fruit Water Extract and Its Application in Indigosol Blue Photodegradation

Abstract

Silver nanoparticles (NPAg) are silver metal particles that are less than 100 nm in size. NPAg has several advantages, one of which is as a catalyst in the process of photodegradation. NPAg was obtained by reducing AgNO3 using andaliman fruit water extract (Zanthoxylum acanthopodium DC.). This synthesis method is very effective because it is fast, non-toxic and environmentally friendly technology. This research aims to synthesize optimum NPAg and its application in the photodegradation process of Indigosol Blue in the form of volume, irradiation time, and optimum pH. NPAg synthesis was observed using a UV-VIS spectrophotometer while its size was observed using PSA (Particle Size Analyzer). The results showed the best NPAg synthesized using 1x10-3 M AgNO3 at 60°C with average NPAg size of 9.04 nm. NPAg which is formed is stable for ± 35 days. The optimum condition for the photodegradation process was achieved by using 2 mL NPAg 4 hour irradiation at pH 3. From the results of this study it can be concluded that NPAg can to reduce the concentration of Indigosol Blue dye by up to 94.75%.
