Produced water is the largest waste stream generated in oil and gas industries. The disposal of this hypersaline wastewaters containing a mixture of different organic and inorganic compounds is a relevant issue. In this study the removal of total suspended solids (TSS) from a real Produced Water, sampled at a full scale oil refinery plant, was optimized. Coagulation experiments were conducted s...

The haemolytic activity of iron-dextran complex is found to be a function of time, temperature, pH, and concentration. The lytic action is enhanced by small amounts of added ferrous sulphate. The lytic action is inhibited by chelating agents such as citrate and sequestrene salts, which bind ionic iron, but not by ferric citrate or ferric sequestrene which do not bind iron. The ionised iron cont...

Reduction of ferric iron in the presence of HuTu 80 cells or duodenal microvillus membranes (MVMs) was investigated. With both systems, NADH-dependent reduction of Fe3+/NTA (nitrilotriacetic acid) was demonstrated, using the ferrous iron chelator ferrozine. Uptake of Fe3+ from Fe3+/NTA by HuTu 80 cells was strongly inhibited by addition of ferrozine, indicating that Fe2+ is the substrate for th...

Polymeric aluminum ferric sulphate(PAFS) was prepared from high-sulfur bauxite flotation tailings and red mud by roasting, acid leaching polymerization. The effects of temperature, time, liquid-solid ratio on the rate Al3+ Fe3+were investigated. optimal conditions are as follows: temperature 100℃, time 90 min, sulfuric concentration 4.5mol/L 5 mg/L. Infrared spectroscopy X-ray diffraction analy...

Bare root transplants of strawberry (Fragaria x ananassa Duch. cv. ‘Selva’) were transferred to nutrient solutions with or without iron (Fe). After six weeks of growth, plants in the solution without Fe were chlorotic and had morphological changes in roots typical of Fe deficiency. At this point, four treatments were imposed with three replicates (plants) each: plants always grown without Fe (F...

Background: The compositions of Ferrous sulphate, Agarose and Xylenol orange dye (FAX) and Ferrous sulphate, Gelatin and Xylenol orange dye (FGX) in solution of distilled water and sulphuric acid are two tissue-equivalent gel dosimeters. Ionizing radiation causes oxidation of Fe ion to Fe ions which diffuse through the gel matrix and blur the image of absorbed dose over a period of hours after ...
