Ekstraksi dan Identifikasi Komponen Utama Pasir Putih dari Desa Marinsow Kabupaten Minahasa Utara dengan Pengujian XRF dan XRD

Abstract

North Sulawesi is one of the regions in Indonesia which has a wealth of natural resources which is quite abundant, one of the natural potential that can be utilized is White sand. White sand has a composition that is SiO2, CaO, Fe2O3, TiO2, MgO. This study aims to identify the composition of the main components of white sand through XRF testing and the results of extraction of white sand from Marinsow village using the alkaline fusion method, NaOH solution for extracting and crystallizing the formation of silica crystals and tested using XRD testing to determine the crystal characteristics. Extraction and testing processes have been carried out using XRF and XRD on white sand samples taken in Marinsow Village, North Minahasa Regency. The results of the identification of the components of the white sand constituents through XRF testing namely CaO is the largest main component of the white sand compilers in the village of Marinsow which is as much as 89.97%. The content of SiO2 compounds in white sand (Marinsow) is as much as 1.41%. Other components found in white sand from Marinsow village, North Minahasa Regency include MgO as much as 5.85%, SrO as much as 2.31%, Fe2O3 as much as 0.277 %, TiO2 is 0.079%, Cr2O3 is 0.032%, Nb2O5 is 0.0238%, MoO3 is 0.0159%, SnO2 is 0.0082%, Sb2O3 is 0.0079% and RuO4 is 0.0074%. The results of XRD testing on white sand taken in the village of Marinsow give results that white sand has a calcite crystal structure (CaO) and for the SiO2 silica component is quartz.

Characterization of silica (SiO₂) based on beach sand from Sulawesi and Sumatra as silicon carbide (SiC) base material

“…This is due to the composition of its constituent oxides having a SiO 2 content that is more dominant than others or having a SiO 2 content of more than 50 %. Similar results have been obtained by Langi et al that the beach sand from Marinsow Village, Minahasa Regency, is dominated by CaO while the SiO 2 content is low at 1.41 % [25]. Joni and Ariyanto also found sand on Camplong beach, dominantly Si, while on the coast of Nepa and Mandangin island, Ca dominant [29].…”

“…Beach sand with distilled water and cleaned or separated from impurities and then dried for 1 -2 days in direct sunlight. The beach sand was ground using a mortar and pestle and then sieved using a 40 mesh sieve [25].…”

“…A total of 50 g of sieved beach sand powder was soaked with 100 cm 3 of 20 % HCl in a beaker glass for 14 hours to dissolve various impurities in the sand. The choice of 20 % HCl with a concentration of 6.5 mol Meytij Jeanne Rampe, Johny Zeth Lombok, Vistarani Arini Tiwow, Soenandar Milian Tompunu Tengker, Jeniver Bua dm -3 follows previous research by Langi et al [25]. 100 cm 3 of 20 % (6.5 mol dm -3 ) hydrochloric acid solution was obtained by diluting 37 % (11.9 mol dm -3 ) hydrochloric acid with a volume of 54.05 cm 3 .…”

Analysis of Mountain Sand Material Content in Rumah Tiga and Hative Besar Villages, Teluk Ambon District Using X-Ray Diffraction (XRD) and X-Ray Fluorescence (XRF) Methods)

“…Analysis of mineral content and lattice parameters/crystal size on mountain sand in Wailete, Hative Besar Village, and Kota Jawa, Rumahtiga Village, was carried out using the XRD method (Muliawan et al, 2019a;Muliawan et al, 2019b). Meanwhile, the analysis of the percentage of elemental and oxide content that forms a mountain sand material in Wailete, Hative Besar Village, and Kota Jawa, Rumahtiga Village, was carried out using the XRF method (Suastika et al, 2018;Langi et al, 2020;Kono et al, 2021).…”

Extraction of Silica (SiO2) from White Sand, Sulawesi Island

“…The white sand is first washed with distilled water and then cleaned/separated from impurities. White sand is ground using a mortar and pestle, then sieved with a 40 mesh sieve [4].…”
