Iodate reduction
Webmediated iodate reduction. S ediments that were pretreated with 2% gluteraldehyde for 7 days to decrease microbial activity and resulted in a 9-fold decrease in the iodate reduction rate, implying some microbial contribution to the overall iodate reduction. Sediments that were pretreated with 5% peroxide to oxidize Web1 nov. 2015 · Bacterial interactions with iodine have been studied, and show that iodate can be reduced directly by iron- and sulfate-reducing bacteria under axenic conditions. Indeed, in one early study, sulfate-reducing species were able to reduce up to 96% of iodate to iodide in matter of hours ( Councell et al., 1997 ).

WebAs the precisely weighed (and now reduced) iodate is titrated with thiosulfate solution in the process of standardizing it, the solution first turns a dark red, then orange, then yellow. The titration showed here on the left and right illustrates the colors you can expect to see during the progress of this standardization titration.
