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

Phosphoric acid can be formed from bone waste, including cow bone which contains calcium phosphate. When reacted with sulfuric acid it becomes phosphoric acid. The purpose of this research was to determine the reaction constant of phosphoric acid from cow bones. The reaction constant can determine the good operating conditions in a reactor design. Starting with the cow bones that have been powdered with a size of 200 mesh, dissolved in the water until saturated. Then saturated solution 500 ml was taken and reacted with 4 N sulfuric acid 100 ml, stirring process was carried out at 200 rpm, with variable temperature were (70oC, 80oC, 90oC, 100oC, and 110oC) and time were (40, 50, 60, 70, and 80 minutes). Next, the sample was filtered, and the sediment was taken, and analysed of phosphoric acid filter and separated the sediment. Based on this research, an equation k = 1.1627 e -3742.4 / T was generated. The graph in picture 5 shows that the equation followed a pseudo first order reaction.
