Why Cr6+ must be reduced
-
highly irritating to skin
-
allergic skin reactions
-
causes ulcers
-
Cr6+ 100 times more toxic than Cr3+, cytotoxicity: 100 - 1000
-
leaching from raw concrete into drinking water
-
highly toxic to fish (food chain protection)
MIG methods of chromate reduction
Modified Tin (II) Sulfate
-
highest reduction power
-
easy to dose due to free flowing powder
-
only about 13 g per ppm Cr6+ per ton
-
neutral formulation
Antimony (III) Oxide
-
free flowing powder
-
dust-bound masterbatch
-
builds an insoluble complex
-
low costs
