This method is based on the precipitation of sulfate ion in such a manner as to form compound sulfate crystals of uniform size.
Turbidimetric Photometric Method (0-50ppm)
Principle / Concept
This method is based on the precipitation of sulfate ion in a hydrochloric acid medium with barium chloride in such a manner as to form barium sulfate crystals of uniform size. The glycerol sulfate solution is used to maintain proper crystal size, and control of the stirring and waiting times is necessary to obtain reproducible result.
