Silica Synthesis from Mount Semeru Volcanic Ash as a Nickel Heavy Metal Adsorbent

This study aims to synthesize SiO2 gel-based adsorbents using the sol-gel method from Mount Semeru volcanic ash through varying concentrations of sodium hydroxide and acid catalysts and to determine its adsorption capacity on nickel (Ni(II)). Volcanic ash was obtained from Lumajang District, East Ja...
