TCEQ Method 10


Determination of Chlorine and/or chlorides in Stack Gas, (Turbidimetric Method)

Chlorine (Cl2) and chlorides (HCl)are trapped in an impinger containing alkaline arsenite solution which reduces chlorine to chloride. Gaseous chlorides (HCl) are absorbed in distilled or deionized water. Both solutions are treated with silver nitrate and the resulting turbidity from the formation of insoluble silver chloride is measured on a spectrophotometer at 360 ran.
