Abstract

Silau River, Indonesia, is a river with areas along its banks used for fishing, factories, and transportation to the sea. The sand from the Silau River is a valuable resource that can be extracted to produce SiO2, with substantial availability. This study aims to extract SiO2 from Silau River sand and modify it using PVA and TiO2 materials as a photocatalyst for water purification. The extraction of SiO2 from the sand was carried out using the coprecipitation method. The PVA/TiO2/SiO2 composite membrane was synthesized by combining a simple mixing technique for filler preparation with mixing and solidification processes to form the composite membrane. Instruments used in this study include a Scanning Electron Microscope-Energy Dispersive X-Ray Spectroscopy (SEM-EDS), Fourier Transform Infrared Spectroscopy (FTIR), X-Ray Diffractometer (XRD), Differential Scanning Calorimetry (DSC), and UV–Vis Spectroscopy. All characterization results indicate that PVA/TiO₂/SiO₂ has been successfully synthesized in every composition variation. The PVA/80 % TiO₂/20 % SiO₂ composite demonstrated the most effective performance, achieving 65.1 % color degradation in river water within 10 hours. Furthermore, the river water parameters, including TDS, turbidity, pH, Cr, Fe, and Mg, which initially failed to meet quality standards, improved after treatment with this composite, enabling the water to meet the quality standards outlined in Government Regulation No. 22 of 2021 of the Republic of Indonesia concerning the Implementation of Environmental Protection and Management.

从Silau河衍生的SiO2: PVA/TiO2/SiO2制备可持续光催化剂用于水净化
印度尼西亚的西劳河是一条河流,沿岸地区用于捕鱼、工厂和出海运输。来自Silau河的沙子是一种宝贵的资源,可以提取出大量的二氧化硅。本研究旨在从Silau河砂中提取SiO2,并使用PVA和TiO2材料对其进行改性,作为光催化剂进行水净化。采用共沉淀法从砂中提取SiO2。采用简单的填料混合制备技术,结合混合固化工艺,制备了PVA/TiO2/SiO2复合膜。本研究使用的仪器包括扫描电子显微镜-能量色散x射线能谱仪(SEM-EDS)、傅里叶变换红外光谱仪(FTIR)、x射线衍射仪(XRD)、差示扫描量热仪(DSC)和紫外可见光谱仪。所有表征结果表明,PVA/TiO₂/SiO₂在每种组成变化下均成功合成。PVA/ 80% TiO 2 / 20% SiO 2复合材料表现出最有效的性能,在10小时内实现65.1%的河水颜色降解。此外,最初未能达到质量标准的河流水质参数,包括TDS、浊度、pH、Cr、Fe和Mg,经过该复合材料处理后得到改善,使水达到了印度尼西亚共和国关于实施环境保护和管理的政府法规2021年第22号规定的质量标准。
