Data for Green Synthesis of Iron Nanoparticles Using Galinsoga parviflora, Conyza bonariensis and Bidens pilosa leaf extracts, and their Application in Degradation of Organic pollutants

Description

This data was obtained from the green synthesis, and characterization of iron nanoparticles from aqueous leaf extracts of Conyza bonariensis, Bidens pilosa, and Galinsoga parviflora. The iron nanoparticles can be synthesized from the plant extracts using a 0.1 M iron III chloride solution. The iron nanoparticles can be characterized using spectroscopy and microscopy techniques (UV VIS and FTIR spectrophotometers, XRD, and SEM). The data is presented in the form of images, tables, and Microsoft Excel data sheets, among others. This data can be utilized by researchers in the green synthesis of iron nanoparticles, using leaf extracts of Conyza bonariensis, Bidens pilosa, Galinsoga parviflora, or any other plant. In addition, the data can be utilized to compare results from similar studies and even replicate research as presented herein.

Steps to reproduce

Fresh leaves of Galinsoga parviflora, Bidens pilosa, and Conyza bonariensis can be collected, washed with clean water, cut into small pieces, and air dried in the laboratory at 25 degrees for a week or two. The dried leaves can then be milled into powder using a milling machine. The phytochemicals present—phenols and flavonoids—can be quantified using the recommended methods. Extraction can be achieved using plant-distilled water boiled at 80 degrees by mixing the powder with water and then boiling it at 60 degrees for 30 minutes. The brownish color depicts the extracts of the plants, which can be filtered several times with cotton wool and kept at 4 degrees. A 0.1-M ferric chloride solution can be prepared by weighing 13.52 g of iron III chloride and dissolving it in 100 mL of distilled water. The extract and the salt can be mixed in a ratio of 3:1 dropwise, and boiled at room temperature. The black precipitate can be centrifuged and washed to obtain nanoparticles, which can be dried at 60 degrees in an oven. The nanoparticles formed, can be confirmed by scanning the solution in an ultraviolet - visible spectroscopy (UV/VIS) in the range of between 200nm to 700 nm, with distilled water as the blank. The UV/VIS spectra can be analyzed by plotting graphs of absorbance against wavelength. The nature of the absorption spectra between them confirms the formation of iron nanoparticles. The functional groups in the nanoparticles and the extract can also help confirm the formation of the nanoparticles. The scanning electron microscope can help determine the morphological status of the surfaces. X-ray diffraction can help characterize the nanoparticles by studying the crystallinity of the particles. The nanoparticles' ability to degrade the organic dyes and antibiotics can be studied by evaluating the effect of the nanoparticle on the maximum absorption of the organic dyes or antibiotics. The organic dye/antibiotic with a given amount of the nanoparticle can be scanned for a given time as the maximum absorption is studied. This can also be studied by varying the pH, time, dosage, and temperature. Drawings and statistical studies can be evaluated using Origin Pro software. XRD data can be interpreted using the Match! software. The SEM images can be interpreted using imageJ software.
