Influence of Carbonization Conditions on Mg Ion Concentration in Mg (HCO3)2 Solution

Article Preview

Abstract:

In this paper, Mg (HCO3)2 solution, was obtained by the carbonate reaction of Mg (OH)2 solution , using magnesite as raw materials. Mg ion concentration was measured by ICP-AES method. The effect of carbonization temperature, carbonization time, flux of CO2 and agitation speed on the concentration of Mg ion in Mg (HCO3)2 solution was investigated. Results showed that Mg ion concentration reduced with increasing temperature, but increased a little as time went on and flux of CO2 improved. With increasing the agitation speed, Mg ion concentration increased firstly, then decreased, finally remained unchanged. XRD analysis shows that the purity of obtained Mg (HCO3)2 solution is very high.
