Abstract

Salt is one of the community and industrial consumption products that have the main content of sodium chloride (NaCl). The present quality of the salt product contains about 90-93% sodium chloride, and the other is known as an impurities of calcium (Ca), magnesium (Mg), potassium (K) and sulfate (SO4) ions. The presence of these impurities will decrease the quality of the salt product, so a method is needed to decrease the content of impurities in the salt product. One of the methods that can be used to reduce the levels of impurities such as Ca, Mg, K and sulfate (SO4) ions in salt solution is ion exchange method. In this study we studied the effect of cation resin amount (50-150) grams per liter of salt solution and anion solution (150 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: 93.6%,Mg :78.93%, K : 25.00% dan SO4 : 85.47 %at condition of cation resin amount: 150 gram / liter and contact time 25 minutes

Abstract

Bleaching Earth is another term used for a type of clay or clay that has a montmorillonite structure. Activation by means of physics, namely heating, can remove dirt and moisture content in the bleaching soil particles. This study aims to reactivate Spent Bleaching Earth (SBE) so that it does not become waste in the surrounding environment. As well as knowing the results of the characteristics of Reactivated Bleaching Earth (RBE) obtained. The reactivation process consists of 2 stages, namely extraction on SBE with n-hexane and activation using a furnace. The method used was maceration extraction with extraction times of 60, 90, 120, 150, 180 and 210 minutes. And the activation temperature is 500, 550, 600, 650, 700 and 750 ˚C. This research gives the result that thermal activation using the furnace can reactivate SBE so that it can match the existing Bleaching Earth characteristics. The best conditions for RBE based on the National Standardization Agency (BSN) in this study were the extraction time of 120 minutes and an activation temperature of 550 oC with a water content value of 0.1625%, real density 2.2970 gr/mL, pH 7.1, and yield. SEM is smoother than others.
