The potential silica utilization as an adsorbent continues to develop. In this study, silica was extracted from bamboo leaf ash using the sol-gel method with NaOH and HCl as the main chemicals. The formation of Na-silicate was obtained by refluxing bamboo leaf ash with NaOH at a temperature of 80 °C for 2 h and then adding HCl until the pH was neutral to obtain silica gel. The silica gel is then filtered and heated to obtain bio-silica. The bio-silica is characterized using Scanning Electron Microscope (SEM), Fourier-Transform Infrared Spectroscopy (FTIR), surface area analyzer (SAA), and X-Ray Fluorescence (XRF). The bio-silica application process was carried out on the adsorption of iodine, methylene blue, chloroform, benzene, and ammonia compounds to produce adsorption capacities of 107.6 mg/g, 70.28 mg/g, 2.51%, 14.22%, 15.7%, and 19.46. %. In the future, silica from natural material waste such as bamboo can be an alternative adsorbent for various adsorption processes.

摘要

The potential silica utilization as an adsorbent continues to develop. In this study, silica was extracted from bamboo leaf ash using the sol-gel method with NaOH and HCl as the main chemicals. The formation of Na-silicate was obtained by refluxing bamboo leaf ash with NaOH at a temperature of 80 °C for 2 h and then adding HCl until the pH was neutral to obtain silica gel. The silica gel is then filtered and heated to obtain bio-silica. The bio-silica is characterized using Scanning Electron Microscope (SEM), Fourier-Transform Infrared Spectroscopy (FTIR), surface area analyzer (SAA), and X-Ray Fluorescence (XRF). The bio-silica application process was carried out on the adsorption of iodine, methylene blue, chloroform, benzene, and ammonia compounds to produce adsorption capacities of 107.6 mg/g, 70.28 mg/g, 2.51%, 14.22%, 15.7%, and 19.46. %. In the future, silica from natural material waste such as bamboo can be an alternative adsorbent for various adsorption processes.
