Abstract

The aims of this research is to determine the effect of variation concentration of HCl on chemical composition, phase formed, and particle size on pumice powder. Nanosilica is made using the solgel method with NaOH concentration 4 M, H2SO4 5 M and variation concentration of HCl 0,5; 0,75; 1; 1,25 dan 1,5 M. The XRF results showed the greatest chemical composition value in the silica pumice powder sample with a value of 77.80%. This value is higher after synthesis at the highest chemical composition value in the nanosilica sample 1,25 M HCl concentration of 87.05%. The XRD results show a diffractogram of pumice powder samples formed by anorthite and albite phases while in the nanosilica sample 1,25 M HCl concentrates are debated with the amorphous phase. The TEM results show particle size of nanosilic sample 1,25 M HCl concentration is 5 nm with average particle size (12.02 ± 3.23) nm.
