In the contract the scope of the work was stated as follows: Specific Aims: 1). To determine rates of air oxidation of ferrous iron in the presence of SO4^ -2 within the PH range 2-5; 2). To determine rate of ferric iron hydrolysis within the PH range 2-5; 3). To investigate the colloid-chemical properties of hydrolyzed iron (III) Parameters: (Fe^+2), (Fe^+3), H^+), (SO4^ -2), P02; 4). To investigate specific aims 1, 2, and 3 above under the effect of the following catalysts: Mn^+2, Cu^+2, Si (OH)4^3 SiO2 (S), Fe2o3 (S).9423479 bytesapplication/pdfen-USOxygenationFerrow IronTechnical Report
