Treatment of Salt for Food-Grade Using Activated Carbon

Abstract:

The research on the effect of treatment of salt for food-grade using activated carbon has done. The purified salt in this study was obtained from the Bringharjo market, Yogyakarta, Indonesia. The purification of salt has been done using activated carbon with various weights are 2.5, 3, 4 g. Other chemicals used as a material to remove impurities are Na₂C₂O₄ and Na₂CO₃. Activated carbon 2.5 g was the salt product with the level of NaCl is 97.28%. Metal content of the Mg, Ca, Pb, and Cd in salt are 0.02%, 0.019%, 10.33 mg/kg, and 2.055 mg/kg, respectively. As a conclusion is, salt produced with treatment using activated carbon can be used for food grade.
