Analysis for Trivalent and Hexavalent Chrome in wastewater
Analysis for Trivalent and Hexavalent Chrome in wastewater

First, the hexavalent ,chromium, is reduced to ,trivalent, -- not only to reduce its toxicity, but because hexavalent ,chromium, is soluble and not filterable. Then the total ,chromium, is precipitated out, filtered and landfilled rather than remaining in the ,wastewater, -- so it doesn't matter so much whether it could theoretically become hexavalent again under some weird oxidizing condition.
