Low carbon steel has been considered a suitable material for component of the multi-barrier system employed on the geological disposal of high-level radioactive waste (HLW). A non negligible amount of dihydrogen (H2) is expected to be produced over the years within the geological repository due to the anoxic corrosion of metallic materials and also to the water radiolysis. The influence of the ...

Since the ban on use of asbestos due to its carcinogenic properties, removal cement, representing major asbestos-containing waste, has proven be a challenge in most industrial countries. Asbestos-containing products are mainly disposed landfills and have remained untreated. Bioremediation involving bacteria previously reported ability Pseudomonas aeruginosa release iron from flocking waste thro...

Toluidine Blue O (TBO) is a cationic dye which is extensively used in the industries. In the present paper a simple and efficient wet chemical method was introduced for removal of TBO from waste aqueous solution. Magnetic multi-walled carbon nanotubes were synthesized using commercially available multi-wall carbon nanotubes and magnetic iron oxide nanoparticles which were examined for removal o...

The availability of iron controls primary productivity in large areas of the Southern Ocean. Iron is largely supplied via atmospheric dust deposition, melting ice, the weathering of shelf sediments, upwelling, sediment resuspension, mixing (deep water, biogenic, and vertical mixing) and hydrothermal vents with varying degrees of temporal and spatial importance. However, large areas of the South...

Decorative ceramic brick for interior decoration is one of the most modern trends in architecture and construction. This type masonry, facing wall materials, which became popular middle last century, becoming more widespread over time. In order to expand disposal industrial waste, issues using iron ore recycling products together with other waste technology materials were considered. The functi...

Leaching of Arsenic from high Arsenic loaded iron oxide impregnated brick sands (IOI CBCM) was investigated using common household chemicals like common salt and soda ash, the industrial chemicals caustic soda and the phosphates used as fertilizers such as potassium hydrogen phosphate and TSP. Leaching by ordinary ground water was also investigated on the arsenic saturated iron oxide impregnate...

Acid drainage is most common problem or associated with almost all mines containing sulphide deposits and coal containing high pyrite. Acid drainage is caused when rain water and or seepage from rock formation interact with sulphur bearing minerals. It produces water of high acidity with higher metal concentration. Acid drainage is most susceptible to dissolve heavy metals particularly Iron, Zi...

The practical application of the Fenton-based treatment method for organic compounds-contaminated water purification is limited mainly because of the large amount of ferric sludge formed during the treatment, where ferrous iron (Fe(II)) is used as the activator of the hydrogen peroxide oxidation processes. Reuse of ferric sludge collected from clarifiers to substitute Fe(II) salts allows reduci...
