Sintesis Nanopartikel Au-SiO2 Menggunakan Natrium Silikat dari Abu Ampas Tebu (AAT)

Abstract: Sintesis nanopartikel Au-SiO2 telah dilakukan dengan menggunakan larutan natrium silikat dari abu ampas tebu (AAT) sebagai sumber utama silika. Tujuan penelitian ini untuk menentukan rasio mol Au:Si dalam nanopartikel Au-SiO2 yang relatif stabil, dapat diamati dari panjang gelombang maksimum dan penentuan full width half maximum (FWHM). Jenis penelitian yang dilakukan adalah penelitian eksperimental. Penelitian ini melalui tahapan yaitu sintesis natrium silikat dari abu ampas tebu, sintesis nanopartikel Au-SiO… Show more

“…The mixture was stirred for 2 h and washed with demineralized water until neutral pH was achieved. Second, the ash interacted with 20 mL of 0.1 M Na2EDTA solution to remove impurities still left behind because Na2EDTA is a metal ion chelating agent (Aini and Amaria, 2022). The ash was rinsed with demineralized water to neutral pH.…”
