Abstract

Salt product of Indonesian country is produced through the process of evaporation and crystallization of seawater. The salt product contains sodium chloride (NaCl) levels ranging between 80-92% and the other are impurities such as magnesium chloride (MgCl2), calcium carbonate (CaCO3), potassium chloride (KCl) and magnesium sulfate (MgSO4). The quality of salt produced has lower quality compared to salt consumption and industry standards, The salt for salt consumption, minimum sodium chloride (NaCl)contain is 94.7%, industrial is more than 98% and pharmaceuticals more than 99.5%. therefore is needed a method to improve the quality of the salt. In this research is selected ion exchange method to improvement the quality of salt. This research focuses on study the effect of cationic resins amount (50-150) grams per liter of salt solution and anion solution (75 grams) and contact time (5-25) minutes on removal of Ca, Mg, K and SO4 ions. The study was conducted in a stirred tank with a fixed rotation speed of 200 rpm, and the initial quality of the salt solution contained Ca ions: 0.07%, Mg: 0.09%, K: 0.04% and SO4: 0.4%. Based on the result of the research, the removal of Ca ion: 82.86%, Mg: 62.22%, K: 25.00% and SO4: 72.50% at condition of cationic resins amount: 100 gram / liter and contact time 25 minutes.
