Principle
Fast digestion-spectrophotometric method
In the acid solution, trivalent chromium can be oxidized into hexavalent chromium. Hexavalent chromium will react with color developing agent and produce purplish-red compound.
Application
Inlet and outlet of municipal wastewater and industrial wastewater; surface water;
Characteristics
