    Dissolved oxygen related to redox potential

    Okay I see the oxygen as a limiting reactant idea now and that makes sense, it's simpler than I was making it out to be. I'll try to restate the second part of my question. If I had some Fe203 in an anaerobic solution could it change to Fe304? Could it take an electron from H20 somehow...

    Dissolved oxygen related to redox potential

    I have read a little bit about some industries deaerating water used in boilers made of iron to prevent them from becoming damaged. I think this is because removing dissolved oxygen from the water lowers its redox potential. I think that this works because once the redox potential of the...

    Chloramination and detecting chloramine with a total chlorine test.

    Chemisttree, thank you, this was very interesting and helpful. As I said I had been mixing the ammonia and chlorine with an excess of Cl but now I have tried it with an excess of ammonia as Audrieth and Rowe suggest in that paper. As might be expected the final mixture still has a lot of ammonia...

    Chloramination and detecting chloramine with a total chlorine test.

    Chloramines are produced by the reaction between ammonia and chlorine like this, NH3 + HOCl → NH2Cl + H2O I have read papers on water treatment that say that in application you need about 10mg of chlorine to react with each 1mg of ammonia. Using a jug of household ammonia and a jug of...

    Oxidizing iron bacteria made to work in reverse

    If it helps I'll link to an article by Toni A. M. Bridge and D. Barrie Johnson http://aem.asm.org/cgi/content/abstract/64/6/2181?maxtoshow=&HITS=10&hits=10&RESULTFORMAT=&titleabstract=iron+bacteria&searchid=1&FIRSTINDEX=0&resourcetype=HWCIT This describes the process I'd like to emulate...

    Oxidizing iron bacteria made to work in reverse

    My employer operates a biological water filtration plant. The first stage of filtration has the raw water passing through a filter embedded with bacteria, the processes used here is aerated biological treatment where oxidizing processes (bio-oxidation) are used and the microbes gain energy when...
