Abstract
Nanočestice se mogu koristiti u medicini, tekstilnoj industriji, elektronici i brojnim drugim područjima korisnima za čovjeka. U njihovoj sintezi se sve više koristi postupak zelene sinteze jer je jeftin i ekološki prihvatljiv. U ovom radu provedena je zelena sinteza nanočestica srebra iz vodenog ekstrakta jednoga od dijelova ploda oraha (pregrade) i vodene otopine AgNO3. Dobivene nanočestice srebra karakterizirane su FT-IR analizom, UV-Vis spektroskopijom te rendgenskom difrakcijom na prahu – PXRD. Dobiveni su rezultati ukazali na uspješnu sintezu nanočestica srebra. Apsorpcijski maksimum nalazio se na približno 420 nm. Veličina sintetiziranih nanočestica izračunata uz pomoć Scherrer-ove formule iznosila je 9 nanometara. Rezultati FT-IR analize ukazali su na biomolekule odgovorne za uspješnu sintezu nanočestica srebra.
Abstract (english)
Nanoparticles can be used in medicine, textile industry, electronic industry and many other fields useful to humans. The green synthesis is becoming more common in the synthesis of silver nanoparticles because it is cheaper and more ecologically acceptable. In this work, green synthesis of silver nanoparticles was conducted using aqueous extract of a part of a walnut fruit (partitions) and silver nitrate – aqueous solution of AgNO3. Synthesized silver nanoparticles were characterized using FT-IR analysis, UV-visible spectrophotometry and powder X-ray diffraction - PXRD. The results show that silver nanoparticles were produced successfully. The absorption maximum occurs at approximately 420 nm. The size of silver nanoparticles is 9 nm, which was determined using Scherrer's equation. The results of FTIR analysis show which biomolecules are responsible for a successful synthesis of nanoparticles.
