ZHYQ 0135 Type Online Automatic Monitor of Total Chromium

Summarize

Chromium is a metal with silver luster, nontoxic and stable chemical property. Stainless steel contains more than 12% chromium. Common chromium compounds include hexavalent chromic anhydride, potassium dichromate, sodium dichromate, potassium chromate and sodium chromate; trivalent chromium sesquioxide (chrome green, Cr2O3); and bivalent chromium oxide. In the chromium compounds, the hexavalent chromium is the most toxic and tervalent chromium takes the second place.

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;
