Abstract
Abstract.Nanoparticle of silica from pumice rockhas been synthesizedby using extracted method of NaOH with varying of 2,5 Mand 3,5 M.The pumice was extracted using NaOH, silica titration usingH 2 and purification of silica using HCl. The solution was calcination at 700°C for 2 hours. The XRD result showed that diffraction pattern of amorphous silica. The EDS result confirmed the purity of silica for NaOH 3,5 M were 75,84%. Particle size from TEM result is(11,32 ± 0,922) nm for NaOH 3,5 M. The surface area for NaOH of 2,5 M and 3,5 M are 178,7 m 2 /g and186,2m 2 /g respectively. Keywords :pumice, nanosilica, NaOH and surface area.
