Silver nanoparticles have received

Silver nanoparticles have received intense attention due to their wide range application in various fields such as medicine, cosmetic and antimicrobial agents, especially antibacterial agent. In recent years, a biological method using plant extracts as reducing agents for the preparation of metallic nanoparticles have been reported. The biological method offers many advantages for the synthesis such as environmental benign, cost-effective process and easily scaled up for large synthesis. As a result, the interest in this research will be studied on the synthesis of silver nanoparticles from the reaction between Jatropha curcas leaf extract and 1.00 mM silver nitrate aqueous solution in varied rations which were 0.10 : 10.00, 0.50 : 10.00 และ 1.00 : 10.00 v/v. The mixtures were kept at ambient temperature, 40 and 80 ˚C for 30 minutes - 72 hours. The formation of silver nanoparticles was followed by using UV-Visible spectrometry which exhibited the absorption spectrum in a range of 410-460 nm. Infrared spectrum of the synthesized silver nanoparticles revealed the presence of organic residues, suggested the reduing and capping roles of the organic species in Jatropha curcas leaf extract.

Silwer nanopartikels het intense aandag ontvang as gevolg van hul wye reeks aansoek in verskeie velde soos medisyne, kosmetiese en antimikrobiese middels, veral antibakteriese agent. In die afgelope jaar, 'n biologiese metode met plant ekstrakte as reduseermiddels vir die voorbereiding van metaal-nanopartikels is aangemeld. . Die biologiese metode bied baie voordele vir die sintese soos omgewing benigne, koste-effektiewe proses en maklik afgeskaal up vir 'n groot sintese. As gevolg hiervan, sal die belangstelling in hierdie navorsing op die sintese van silwer nanopartikels van die reaksie tussen Jatropha bestudeer word. . Curcas blaar uittreksel en 1.00 mm silwernitraat waterige oplossing in verskillende rantsoene wat 0.10: 10.00, 0.50: 10.00 en 1.00: 10.00 v / v Die mengsel is op die omringende temperatuur, 40 en 80 C gehou vir 30 minute - 72 uur. Die vorming van silwer nanopartikels is gevolg deur die gebruik van UV-sigbare spektrometrie wat uitgestal die absorpsiespektrum in 'n reeks van 410-460 nm. Infrarooi spektrum van die gesintetiseer silwer nanopartikels het die teenwoordigheid van organiese reste, het voorgestel dat die reduing en die beperking van rolle van die organiese. spesies in Jatropha Curcas Leaf Extract.
