Improved Strategies for Dollar Spot Suppression Using Ferrous Sulfate
… disease. Previous research has demonstrated that ferrous sulfate applied at 48.8 kg ha-1 suppresses dollar spot epidemics without traditional fungicides. In vitro studies showed 100 to 1,000 mg kg-1 of ferrous sulfate directly suppressed S. homoeocarpa growth of an isolate collected from an …

Polarography applied to nitrate determination in sanitary water analysis
… obtained indicated that ferric chloride, ferric sulfate, chlorine, and copper sulfate did not interfere with the nitrate analysis. Alum and ferrous sulfate caused a significant interference. The loss in nitrate recovery due to the presence of alum in solution was found to be directly proportional …

Evaluation of iron valence state alterations in thermally processed liquid model systems
… system fortified with 24 ppm of iron as either ferrous sulfate, ferric orthophosphate or ferric orthophosphate + 110 ppm ascorbic acid was thermally processed as 240, 250 and 260°F for 3, 6, 9, 12 and 15 minutes. Levels of elemental, nonelemental, soluble, total ionic and ferrous iron were …

Exploring Metallic Flavor Perception: Analysis of Human Salivary Proteins and the Use of the Iron-Binding Protein Lactoferrin in Reducing Metallic Off-Flavors
… and water. Metallic off-flavor, induced by ferrous sulfate solution (10mg/L), and its remediation using pre- and post-rinse treatments of water (control) or metal chelators, were studied. Metal chelators included lactoferrin (1 ?M), a natural metal-binding protein in milk and saliva, and …

FACTORS AFFECTING THE AVAILABILITY OF IRON IN WHEAT BRAN AND PEA BRAN
… flour diets were fortified with 18 ppm iron as ferrous sulfate. The bioavailability of iron was evaluated by comparing the hemoglobin-iron gain per intake of iron (hemoglobin efficiency) of the rats fed the test diets with the hemoglobin efficiency of rats fed a basal diet fortified with 18 ppm …

The Interaction of Iron with Proteins and Sugars in Biological Fluids and Beverages
… taste interaction between sucrose and ferrous ions significantly (p<0.05) increased the acceptance of very hard water (3 mg Fe/L). The sweet-metallic interaction created a unique selection of the emotional term 'mild'. High iron concentration in bovine drinking water (2 mg Fe/L or …

Ferric chloride from crude copperas
Ferrous sulfate, commercially known as copperas, is a by-product of many industries such as the steel industry where steel is “pickled” in sulfuric acid previous to galvanizing, and in ore refining where sulfuric acid is used to remove undesirable impurities consisting chiefly of iron materials. …

High-Intensity Shear as a Wet Sludge Disintegration Technology and a Mechanism for Floc Structure Analysis
… trends were not observed in reactors dosed with ferrous iron. Preliminary results suggest that the ferric/ferrous redox chemistry may serve to enhance floc structure, as observed by increased settling velocity and shear resistance for sludges dosed with ferrous sulfate.

Selected Aspects of Mineral Nutriture of the Cat and Dog With Special Emphasis on Magnesium and Iron
… approximately three times more efficiently than ferrous sulfate and ten times more efficiently than corn gluten meal Fe. The bioavailability of Fe supplied by common feed ingredients of plant and animal origin was estimated by chick hemoglobin repletion assays, including sesame seed meal (96%), …

Evaluating Methods of Improving Recovery of Sub-lethally Injured Salmonella in Low Moisture Foods Treated with Antimicrobial Gas
… In further studies, addition of sodium pyruvate, ferrous sulfate, or 3'3'-thiodiproionate supplements to MTSAYE did not show increased recovery (P>0.05). On each treatment and LMF combination tested, there was no significant difference between the log reduction of S. enterica and E. faecium NRRL …

Novel methods for identification and quantification of iron fortificants in cereal flours
… Fe/kg flour using ferric pyrophosphate (FePP), ferrous sulfate (FeSO4), ferrous citrate (FeCit), ferrous fumarate (FeFum), sodium ferric EDTA (NaFeEDTA), and electrolytic iron (EFe). Using potassium thiocyanate (KSCN) with HCl with and without hydrogen peroxide (H2O2), we identified EFe, ferric, …

Applications of microwave technology to wastewater treatment
… processes, with and without an addition of ferrous sulfate (MW/H₂O₂-AOP and MW/H₂O₂/Fe+²-AOP), were also studied for reducing solids, and solubilizing nutrients from the secondary sewage sludge. For the MW/H₂O₂/Fe+²-AOP, the best results of solubilization, in terms of orthophosphate, ammonia …
