Description 1415-1421
Present investigation consists the green nanoparticles prepared by using both fresh and dry marine macroalga of Padina boeregeseni was reported and the physical and chemical factors such as time duration, pH, various mixing ratios of aqueous extract to AgNO3 solution and temperature that play vital role in the nanoparticles synthesis were assess. Maximum synthesis of silver nanoparticles was attained within 30 min at pH 8.5, 70°C and 1mM AgNO3. Characterization of silver nanoparticles was carried out based on UV-Vis spectrophotometry (418 nm). The size of nanoparticles synthesis with average of 43.3 nm was confirmed by scanning electron microscopy (SEM). X-ray diffraction (XRD) crystallography illustrated the silver nanoparticles crystalline nature. Fourier transform infrared spectroscopy (FTIR) shows that the function groups are hydroxyl, carbonyl, amine and phenol compounds of extract P.boeregeseni are involved in the reduction of aqueous AgNO3. This method of Ag-NPs synthesis does not use any toxic reagents and thus has potential for use in biomedical and agricultural application.
