VERFAHREN ZUR BESTIMMUNG DES CARBONATGEHALTS VON WASCHSUSPENSIONEN

摘要

The method for determining the carbonate content of wash suspensions of flue gas desulfurisation plants employing limestone is carried out by first adding a quantity of iron(III) chloride solution exceeding the maximum possible sulfite content to samples heated to 40 to 70 DEG C and determining the quantity of gas released and corresponding to the carbonate content after oxidising the sulfite to sulfate by adding excess sulfuric acid or other acids.
