ABSTRACT:
The chloride ion and carbonate ion concentrations of a strongly alkaline solution can be reduced by the process of mixing sodium aluminosilicate into the solution, heating the resulting solution to a temperature of at least 90 degrees Celsius to form a sodalite type product, and filtering the sodalite type product from the solution.
