Environmental Method for Synthesizing Amorphous Silica Oxide Nanoparticles from a Natural Material

Abstract

Numerous studies have been performed on the generation of several silicon-based engineering materials that often have used chemical materials that have high risks for health and the safety of the environment. Generally, in the synthesis of Nano-silica, tetramethoxysilane, tetraethoxysilane, and tetraethyl orthosilicate (TEOS) are used as precursor materials; however, these materials are toxic and expensive for the production of Nano-silica. This paper presents an environmentally friendly short method (EFSM) with high efficiency for the synthesis of amorphous silica oxide Nanoparticles by using agricultural waste called rice husks (RHs). Use of the EFSM method as an alternative to the chemical methods would have the advantages of fast and simple operation, controllability, great pureness of the Nanoparticles, and low manufacturing cost. A Nanoparticles (NPs) evaluation was conducted with energy-dispersive spectroscopy (EDS), field emission scanning electron microscope (FESEM) and X-ray fluorescence (XRF). By applying the EFSM method, non-toxic amorphous silica nanoparticles with a purity of 94.5% and particle size less than 100 nm was synthesized without using any chemical material.

Current Challenges and Advancements on the Management of Water Retreatment in Different Production Operations of Shale Reservoirs

“…As the produced water contains hazardous materials and can pose significant environmental problems, it cannot be reused without retreatment [21][22][23][24][25][26][27][28][29][30]. Therefore, the use of treated water to continue the operations should be strictly promoted by the World Health Organization to [31][32][33][34][35][36][37][38][39][40]. These hazardous materials consisted of solid and heavy metals, chemical agents in produced water that might be highly toxic to the environment [41][42][43][44][45][46][47][48][49][50][51].…”

Selain itu, proses kalsinasi dengan suhu dan laju pemanasan dalam proses sintesis silika seam padi memiliki pengaruh yang signifikan terhadap bentuk dan ukuran nanopartikel (Zarei et al, 2021).…”

Biogenic Nanoparticles: Synthesis, Characterisation and Applications

“…Such NPs form the next generation building blocks for biomedical [6], chemical, electronic and optical applications [7]. In recent years, nanoparticles have also found applications in the environmental [8,9], petroleum [10,11], food [12] and textile industries [13]. Whereas, in the past metal nanoparticles such as gold and silver were studied in great detail, the last decade has seen the rise Appl.…”
