  • Fatty Acid Methyl Esters (FAME)

    Fatty Acid Methyl Esters (FAME) are esters of fatty acids The physical characteristics of fatty acid esters are closer to those of fossil diesel fuels than pure vegetable oils, but properties depend on the type of vegetable oil A mixture of different fatty acid methyl ,...

  • Iron Oxide Nanoparticles

    Iron oxide nanoparticles tend to aggregate due to their large surface to volume ratio exhibiting strong supraparamagnetic properti Physiochemical properties such as the particle size, distribution, and concentration are invaluable for adjusting the optical and magnetic properti Combinatorial therapies assisted by iron oxide nanoparticles are indicated in cancer therapy...

  • Iron Production

    The iron found in iron ores are found in the form of iron oxid As a result of these impurities, iron must be first separated from the gangue and then converted to pure iron This is accomplished by the method of pyrometallurgy, a high temperature process The high temperatures are needed for the reduction of iron and the oxidation of the ....

  • Geochemistry of AMD / ARD

    When sulfidic material is exposed to atmospheric oxygen, sulfide minerals begin to oxidise and water subsequently transports reaction products including acidity, sulfate, iron and other metals into surface water and groundwater This water is referred to as acid and metalliferous drainage (AMD) or acid ,...

  • 10 What is Steel Pickling

    10 WHAT IS STEEL PICKLING? 11 The History 111 Lemon Juice and Vinegar Acid has been used to clean metals for centuries, both in the home and in industry In the home, weak, safe acids such as vinegar and lemon juice are often used to clean cooking utensils of tarnish, and everyone knows that Coca-Cola is a good rust remover (it...

  • Extraction of Gold

    Ferrous chloride and sulphate, arsenious acid, antimonious acid, and stannous chloride throw it down as a brown powder of varying degrees of subdivision, the precipitate with ferrous chloride being more finely divided when the gold solution is poured into the iron solution than that produced by the reverse method...

  • Hydrochloric acid | HCl

    Hydrochloric acid must be handled with appropriate safety precautions because it is a highly corrosive liqu Hydrochloric acid, or muriatic acid by its historical but still occasionally used name, has been an important and frequently used chemical from early history and was discovered by the alchemist Jabir ibn Hayyan around the year 800...

  • Sodium hypochlorite as a disinfectant

    Sodium hypochlorite is as effective as chlorine gas for disinfection Sodium hypochlorite produces residual disinfectant Disadvantag Sodium hypochlorite is a dangerous and corrosive substance While working with sodium hypochlorite, safety measures have to ,...

  • Acid mine drainage

    Acid mine drainage (AMD) occurs when metal sulfides, most commonly pyrite, are exposed to and react with air and water When water flows over or through sulfur-bearing mine tailings, a chemical reaction occurs between the water and rocks resulting in metal-rich water...

  • Citric Acid

    It is a tricarboxylic acid with pK values of 314, 477 and 639 (for each carboxylic group) Citric acid is water soluble and enhances the flavour of citrus-based foods Citric acid has antimicrobial properties due to its acidulation, but it is also used as an antioxidant indirectly ,...

  • Acetic acid

    Acetic acid, also known as ethanoic acid, is an organic chemical compound best recognized for giving vinegar its sour taste and pungent smell Pure water-free acetic acid (glacial acetic acid) is a colorless hygroscopic liquid and freezes below 167 °C (62 °F) to a colourless crystalline sol Acetic acid is corrosive, and its vapour is irritating to eyes and nose, although it is a weak ....

  • Sulfuric acid | H2SO4

    Sulfuric acid released to air will also be in or on particles that eventually fall to the ground Sulfuric acid contributes to the formation of acid rain It is expected to be broken down by sunlight Sulfuric acid is present in the air mainly from the hydrolysis of sulfur oxides produced by combustion, both natural and burning coal, oil and gas...

  • ACID properties of transactions

    ACID properties of transactions In the context of transaction processing, the acronym ACID refers to the four key properties of a transaction: atomicity, consistency, isolation, and durability Atomicity All changes to data are performed as if they are a single operation That is, all the changes are performed, or none of them are...

  • Iron (Fe) and water

    Iron is essential for nitrogen binding and nitrate reduction, and it may be a limiting factor for phytoplankton growth Solubility in salt water is extremely low The iron cycle means reduction of tertiary iron by organic ligands (a process that is photo catalysed in surface waters), and oxidation of binary iron...
