ABSTRACT:
Reaction heat values of basic aluminum sulfate solution with acid such as sulfuric acid are correlative with an amount of base contained in said solution. The difference of temperatures of said solution before and after its reaction with said acid is utilized as an indication for the calibration of the basic amount in the solution. This calibration is effectively utilized for the control of the basic amount of said solution which is employed in the removal of SO.sub.2 gas from a waste gas.
