Abstract
In this paper, we systematically report the characteristics of nanoparticles (NPs)-SiO2 amorphous, and its application for water treatment. NPs-SiO2 can be obtained from natural quartz sand, then extracted and synthesized using the hydrothermal and co-precipitation method. Has an amorphous phase structure; particle size <80 nm, particle formation tends to form the Si-O-Si chain (like a ring), and has a large porosity. High porosity, and is inert and insoluble, is a ceramic material, is an advantage and is very safe to be applied as a water filter material, in the process of water treatment water consumption. This excellent behavior makes NPs-SiO2 able to absorb heavy metals and dyes that are dissolved in water.
