Abstract
The aim of this research is to increase the concentration of people's salt until the NaCl content meets the SNI for Industrial Salt by reducing the impurity levels of Ca2+ and Mg2+ ions until it reaches levels that comply with the SNI for Industrial Salt. From the results of the analysis that have been obtained and discussed, several conclusions can be drawn as follows: The addition of excess reagents R1 = 25% (0.208 gr Ammonium carbonate) and R2 = 30% (0.304 gr Sodium Oxalate) produces the lowest quality salt, with impurity levels Ca = 0.075% and Mg = 0.05% and NaCl concentration = 92 .00%. The best salt concentration was obtained in the combination of adding excess reagent R1 = 10% (0.183 gr Ammonium carbonate) and R2 = 15% (0.269 gr Sodium Oxalate) to produce salt with a NaCl concentration = 99.24%, Ca content = 0.004% and Mg content = 0.052%. Ammonium Carbonate (R1) and Sodium Oxalate (R2) reagents have been proven to reduce salt impurity levels and increase NaCl concentrations.
