Abstract
Magnesium silicate (MgSiO3) is an inorganic compound formed from the reaction between magnesium and silicate. This study aims to optimize the process of forming magnesium silicate from bittern using the precipitation method. Bittern is a liquid waste from the salt industry that is rich in magnesium ions. In this study, magnesium hydroxide (Mg(OH)₂) was obtained by reacting bittern with sodium hydroxide (NaOH), then further reacted with sodium silicate (Na₂SiO₃) to form magnesium silicate (MgSiO₃). Variations in the molar ratio between NaOH: MgCl₂ and Mg(OH)₂: Na₂SiO₃ were used to determine the optimum conditions in product formation. The results of the analysis showed that the highest yield of 69,969% was obtained at a mole ratio of NaOH: MgCl₂ = 1:2 and Mg(OH)₂: Na₂SiO₃ = 1:1. Characterization using X-Ray Fluorescence (XRF) showed that the optimal composition of magnesium silicate produced contained 17% MgO and 71% SiO₂. This study confirms that optimization of the reactant molar ratio plays an important role in the efficiency of magnesium silicate production, as well as opening up opportunities for its utilization in various industrial applications.
