Abstract
In comparison with bulk materials, nanoparticles possess improved characteristics due to their sizes and morphology, thus, making them invaluable for various industrial applications. This study assesses the effect of contact time and temperature on the green synthesis of silver nanoparticles (AgNPs) from the extract of soursop (Annona Muricata) bark. The optimization factors were studied at a constant concentration of 0.01 M AgNO3 solution, contact time at 20, 40, 60 and 80 minutes and temperature at 30, 40, 50 and 60o C. The AgNPs were synthesized using aqueous extract of bark of soursop plant as bio reducing agent. The formation stability of the reduced silver nanoparticles was characterized using ultraviolet-visible spectrophotometer within the wavelength range of 420-700 nm. This study proves that, AgNPs was successfully synthesized and the optimized conditions for this biosynthesis were; contact time, 40 minutes and temperature, 60o C. This inexpensive and environmentally friendly synthesis can be utilized for the production of silver nanoparticles on a large-scale.
