Environmental issues solution

Observing a brown gas dissolve in water to form an acidic solution has greater relevance to a high school audience when the observation is related to the global problems of atmospheric pollution and acid precipitation. The environmental issues mean more to the students for having seen the demonstrations. [Pg.470]

This paper explores the use of plastics in cars to make them more environmentally friendly. It lists major environmental issues. It then discusses in detail the positive role of plastics during the lifetime of a car (more plastics means less fuel consumption), the fact that automotive plastic parts are user-friendly and safe, the current and future uses of plastics in cars, recovery options for plastics in end-of-life vehicles, mechanical recycling (which is the best recovery option for many large automotive parts), energy recovery (the solution for small plastic parts), and feedstock (or chemical) recycling. Lastly, the way forward is considered. [Pg.90]

The elucidation of actinide chemistry in solution is important for understanding actinide separation and for predicting actinide transport in the environment, particularly with respect to the safety of nuclear waste disposal.72,73 The uranyl CO + ion, for example, has received considerable interest because of its importance for environmental issues and its role as a computational benchmark system for higher actinides. Direct structural information on the coordination of uranyl in aqueous solution has been obtained mainly by extended X-ray absorption fine structure (EXAFS) measurements,74-76 whereas X-ray scattering studies of uranium and actinide solutions are more rare.77 Various ab initio studies of uranyl and related molecules, with a polarizable continuum model to mimic the solvent environment and/or a number of explicit water molecules, have been performed.78-82 We have performed a structural investigation of the carbonate system of dioxouranyl (VI) and (V), [U02(C03)3]4- and [U02(C03)3]5- in water.83 This study showed that only minor geometrical rearrangements occur upon the one-electron reduction of [U02(C03)3]4- to [U02(C03)3]5-, which supports the reversibility of this reduction. [Pg.269]

Cadmium coating was for a while a very good solution for many applications but due to environmental issues can no longer be used. These days other standard satisfactory spring coatings are replacing cadmium depending on the application ... [Pg.248]

Island Press is the only nonprofit organization in the United States whose principal purpose is the publication of books on environmental issues and natural resource management. We provide solutions-oriented information to professionals, public officials, business and community leaders, and concerned citizens who are shaping responses to environmental problems. [Pg.3]

The environmental issues are providing an exciting opportunity for R D to make a significant contribution, not only to the health of the local community but also the financial health of the company. Some of the major areas for study by R D are catalytic solutions, solvent replacement, novel reactors, such as microreactors, as well as considering the product design carrying out life cycle assessments and the use of alternative feedstocks. This area has become known as Green Chemistry [D-6]. [Pg.224]

Scale-up of catalyst manufacturing processes is a multidisciplinary teamwork where science, empirical experiments and knowledge of equipment technology are integrated. Production cost and environmental issues set tight limits on possible manufacturing solutions. A successful work is not frequent, and it can take some years before you really know you have a technological as well as an economical success. [Pg.14]
