Synthesis and Study of Silver Nanoparticles Using Iraqi and Indian Lawsonia inermis Plant and their Catalytic Performance in Degradation of Organic Pollutant


Abstract- In this work, we depict the cheap, friendly environment, anunreported and easy methodology for the synthesis of silver nanoparticlesusing the extract of leaf concentrate of Lawsonia inermis as a green,reducing agent. Silver nanoparticles display exclusive physicalcharacteristics, which have appealed serious research attention due to theiressential uses. In present work, silver nanoparticles were synthesized forenvironment uses by means of a completely green biosynthetic process usingLawsonia inermis flowers extract (henna). The structure, as well asproperties of silver nanoparticles, was investigated with UV-visiblespectroscopic techniques, scanning electron microscopy (SEM), energydispersive X-ray spectrometers (EDS) and zeta potential. The maximumpeak absorption by using UV-visible spectroscopic analysis was found at460and 495nm, which point to the production of silver nanoparticles. Usualslight particle diameter that is determined by SEM was found to (10-46nm).Furthermore, zeta potential investigation shown that silver nanoparticleshave good stability. EDX analysis also displays the presentation of a silverelement. The methylene The catalytic effectiveness using light (LED) withsilver nanoparticles was additionally researched in catalytic degradation ofmethylene blue dye. blue dye degrades 16 - 24.8% within 40 min for Iraqi& Indian henna produced better catalytic activity because of smallerparticle size of silver, which is less than (10 ) nm in Indian henna.
