ABSTRACT
First we will use sand filter to purify dense brine solution and remove flocculent impurities. Then the brine solution is decolorized with chemical reagent.
2.2 Experimental procedure
A certain concentration of strong halide solution and sodium hydroxide solution are prepared, the temperature is raised as required, a certain amount of water is charged into the reactor as the base. Under certain stirring speed, the sodium hydroxide and magnesium chloride solution are feed into the reactor at a certain flow rate.
