Extractions: SEEMINGLY FOR THOUSANDS OF YEARS WATER WAS CONSIDERED TO BE A CLEAR COLOURLESS LIQUID. YES IT HAD SOME UNIQUE PROPERTIES, YES IT IS ALMOST A UNIVERSAL SOLVENT, YES IT IS VITAL FOR LIFE AND YES IT IS A MOLECULE CONSTRUCTED FROM TWO ATOMS OF HYDROGEN AND ONE OF OXYGEN. BUT THAT IS ALL. IT CAN CARRY IMPURITIES (BECAUSE IT IS A SOLVENT) AND YES IT CAN CARRY DISEASE, BECAUSE IT IS NECESSARY FOR LIFE AND EVEN DISEASE CAUSING ORGANISMS ARE LIFE. THIS IS THE SIMPLISTIC AND GENERAL VIEW THAT PERVADES OUR THINKING EVEN TODAY. THUS WE TREAT WATER TO REMOVE IMPURITIES AND KILL DISEASE CAUSING ORGANISMS. BUT AS THE WORLD POPULATION GROWS, THE DEMAND FOR CLEAN PURE HEALTHY WATER GROWS, SO THE SUPPLY SHRINKS ESPECIALLY IN AREAS WHERE THE WATER SUPPLY ITSELF IS OR GETS POLLUTED. DUE TO THIS DEMAND SCIENTISTS AND PEOPLE AROUND THE WORLD ARE LOOKING AT WATER MUCH MORE CLOSELY AND SERIOUSLY. THEY ARE MAKING ASTOUNDING DISCOVERIES AND DOING AMAZING THINGS WITH WATER.

Extractions: permission of Elisabeth Helldörfer , Bayreuth) Most adult dytiscid water beetles (Coleoptera: Dytiscidae ) contain two complex gland systems: Members of the dytiscid subfamilies Dytiscinae (Fig. 1), Colymbetinae (Fig. 2), Hydroporinae and Laccophilinae possess a pair of exocrine glands located underneath the pronotum. In these prothoracic defensive glands predominantly considerable amounts of vertebrate hormone-type steroids are stored ( ). When the beetles are irritated mechanically or seized by a predator, usually a white or yellowish milky fluid emerges from the glands on the anterior margin of the pronotum. It has been shown that prothoracic steroids of dytiscids possess a strong anti-feedant activity against fish ( The pygidial glands on the hindmost abdominal segment contain mainly low molecular aromatic substances like benzoic acid, phenylacetic acid and p -hydroxybenzalde- hyde ( ). The beetles distribute the pygidial secretion on their surface using their hind legs. In addition to their antimicrobial activity, the pygidial compounds result in an increased wettability of the integument, which facilitates re-entry into the water, for example after a flight (

Extractions: A laboratory module designed as an introduction to factors affecting water quality and the methods used to assess water quality. Some techniques require only a buret and a few chemicals, while others utilize sophisticated instrumentation. In an undergraduate setting, the module is designed to take three-to-five weeks; more advanced students can use it in an instrumental methods of analysis course and can delve deeper into the theory and practice of ion chromatography or atomic absorption spectrophotometry.

Extractions: Recall the structural formula of a water molecule: H O, where the oxygen atom shares a pair of electrons with each of the hydrogen atoms (overhead 1.11). In the O-H covalent bonds, however, the shared electrons are not shared equally. They are held closer to the oxygen atom because oxygen has a stronger attraction for electrons than hydrogen does (oxygen has 8 protons in its nucleus; hydrogen has only one). As a result, the oxygen end of the water molecule is slightly negative whereas the hydrogen end has a partial positive charge.

Extractions: Kommentar abgeben From Book News, Inc. New edition of a 1983 reference for professionals involved with water quality and treatment. Coverage includes criteria and standards for drinking water quality, and various methods for removal of organics, inorganics, particulate matter, hardness, corrosive substances, and pathogenic bacteria, viruses, and protozoans. Although discussion does not include the design of water treatment plants, it does emphasize how the chemical aspects of water treatment should influence the design of treatment plants (rather than design being shaped only by hyrdraulic considerations). This edition contains a new chapter on aeration and attempts to assess the chemical and physical efficacies of current processes to meet the demands of the Safe Drinking Water Act of 1986, the criteria and standards of which are outlined in detail. Treatment processes of the future are also discussed. Synopsis This comprehensive text focuses on the chemical aspects of water quality and water treatment that influence the design of treatment processes. Over a decade in the making, "Chemistry of Water Treatment, Second Edition" is completely up-to-date and features an important new chapter on aeriation technology. The book provides critical reference information on the removal of organic and inorganic compounds, heavy metals, particulate matter, pathogenic bacteria, protozoans and viruses. It also...

http://www.photobiology.com/educational/len/part4.htm

Extractions: Back to the previous section 4. RADIATION CHEMISTRY OF WATER The radiation chemistry of water has been studied since the discovery natural radioactivity. Early workers starting with Bequerel observed that radium emanations decompose water into the hydrogen and oxygen. This reaction was explained by dissociation of water molecules into the constituent atoms. Further studies with deaerated water led to the identification of the molecular yield consisting of H and H O which was attributed to the recombination reactions of primary H and OH radicals. The slow decomposition of H O explains the formation of O . The irradiation of inorganic and organic compounds in aqueous solution usually generate more products and higher yields under oxygenated conditions compared to oxygen-free solutions. The enhancing effect of oxygen was attributed by the formation of hydroperoxy radicals HO from reactions of H atoms with molecular oxygen. HO is the acidic form of superoxid e O with p K a = 4.88. This straightforward theory was unchallenged until the early 1960s. Very puzzling questions arose when accurate rate constant measurements with strong gamma-ray sources were inconsistent with the assumption that H atoms are the dominant reducing species in the radiolysis of deaerated water

Extractions: Water - you know your life depends upon it, but how much do you really know about it? Water covers 4/5 of our planet, so it is readily available, yet water is one of the earth's most precious resources. Fresh water is precious not only because we need it to live, but also because only about 3% of all the earth's water is usable. Of the water on earth, only about one percent is available as fresh water for people to use. The majority, 97%, is salt water in the oceans; the rest is locked in the ice caps or groundwater. Water is made from one oxygen atom bound to two hydrogen atoms. The formula for this is H2O. Water is usually found in its liquid state, but is also common in its gaseous state as vapor in the air, or as a solid (frozen). It is the only substance in nature which is commonly found in all three states. As the forms of water change, water moves from the sky to the earth and back to the sky again. This is called the water cycle. For more information on the water cycle, and other water chemistry issues, click on the links below.
