Abstract

An oven microwave was established for synthesis of zinc oxide nanoparticles using Sargassum sp. and Padina sp. extract and 0.1 M ZnCl2 solution as a precursor. The ZnO nanoparticles had been characterized such as chemical structure by Fourier transform infrared (FTIR) spectroscopy, particle size distribution with Particle Size Analyzer (PSA), Scanning Electron Microscopy-Energy Dispersive Spectroscopy (SEMEDS) and crystalline properties with X-ray diffraction (XRD). The result showed that FTIR spectra revealed the involvement of hydroxyl groups and sulfate polysaccharide in the formation of ZnO NPs and protein was involved in stabilizing. PSA analysis showed that the size ranged of ZnO NPs extract Sargassum sp. synthesized 351,14 and 1.336.19 nm for extract Padina sp. The particle size distribution was homogeneous but their size hadn’t met the size of nanometers. The range of %mass elements Zn and O ZnO extract Sargassum sp. and Padina sp. synthesized didn’t approach standard ZnO. The crystallinity properties showed only ZnO extract of Padina sp. synthesized which had a peak with an angle value of 2θ was almost equal to standard ZnO and after confirmed to Match program! 3 crystal structure ZnO synthesized wasn’t imperfect hexagonal wurtzite. Ovens microwave could be used to synthesize ZnO from Padina sp. extract but it was still necessary to develop a method so that ZnO could be obtained with nanoparticle size and ideal hexagonal wurtzit structure.
