Silica nanoparticles (SNPs) have many important applications including anti-reflection coating, self-cleaning surface and drug carriers. They are usually synthesized from the commercial precursor such as tetraethyl orthosilicate (TEOS). On other hand, natural silica can be found abundantly in organic materials rice husk palm shell or inorganic material beach sand clay. Therefore, obtaining SNPs resources is very strategic for economic technology considerations. This motivates current study performing synthesis characterization of derived one available. Fort this purpose, sands were mixed with sodium hydroxide (NaOH) 2 hours at 90⁰ C, prior to filtering process gaining silicate solution (SSS) which was further refluxed hydrochloric acid (HCl) 3 5 M until its pH reached value 7, finally dried. The characterizations carried out on resulting included UV-Vis FTIR spectroscopies, XRD SEM. confirmed that samples amorphous phase average crystallite size 4.8 2.9 nm chloric acid, respectively. image analysis SEM results revealed obtained diameter 11.6-12.00 nm. formation spectroscopies. basis investigation results, it shown desired successfully sand.
