  • The Canary In The River Analysis

    any initiative made by the bureaucracy is beneficial to the awareness of the environmental problem. Due to recent studies bringing questions of the role of waste water treatment and the leaking of endocrine disrupting chemicals into the environment, “The Environment Agency, in collaboration with government and the water industry, has developed a demonstration program to conduct…the effectiveness and associated costs of current sewage treatment technologies for removing steroid hormones from effluent and will also conduct full-scale demonstration trials of the most promising advanced treatment technologies, such as granular activated carbon.” (Gross-Sorokin) This study is promising in that not only will it examine the effectiveness of the wastewater treatment itself, but also the success of a possible solution in granular activated carbon. Finding a low cost solution is almost as important as diagnosing the problem itself. Although answers can be discovered, the implementation of the solution can make or break the success of its usage. Validation is still needed to determine if wastewater treatment plants are the sole outlet that leaks the endocrine disrupting chemicals into the environment. More research needs to be done on the possibility of leakage into the soil from agricultural processes and urban cityscapes. In theory, leakage into the soil could further leak into the water table below. Since most Americans’ drinking water is pumped from the ground water, we…

  • Bullseye Glass Case Analysis

    assessments disagree with Bullseye’s claims. The issue expanded beyond a state wide controversy into a national debate about the role of regulatory agencies and their authority over business and private sector enterprises. While this situation reveals some problematic approaches about how regulatory agencies perform inspections and enforcement of laws, the issue remains clear that Bullseye Glass was in fact in violation of local, state and federal air quality standards. Experts have said that…

  • Sn2 Reaction Essay

     Comment: The three bonds (one solid line, one wedged line and one dashed line) that are attached to the + carbon atom are turned inside out. If the starting material has Br on the right side of the + carbon atom, the final product will have OH on the left side of the + carbon atom and vice versa.  Comment: There is only one hump for the energy profile of an SN2 reaction. As we shall see later, there are two humps for the energy profile of an SN1 reaction. One easy way to…

  • 8.2 Fullerene Synthesis Lab Report

    In September of 1985 Kroto, Heath, O’Brien, Curl, and Smalley were investigating sources of the long carbon chain molecules in the interstellar medium and how they might be related to soot formation.1 Smalley developed a laser vaporization cluster beam apparatus that allowed for the mass-spectrometric study of stable clusters formed in a helium-entrained plasma produced by a pulse of laser aimed on at a solid target.2 This experimental technique was a very important discovery to cluster science…

  • Synthesizing 1-Phenylazo-2-Naphtol Lab Report

    of 0.54g. Through soaking a fabric with the phenyldiazonium chloride dye, its ingrain property was also determined. The experiment was able to synthesize the desired products and is considered a success. I. Introduction Azo dyes are organic compounds that are able to show bright and intense colors, mostly red, yellow and orange or somewhere in between. As the name suggests, these compounds contain azo linkages, -N=N-, which are responsible for the compound’s coloring or dyeing properties. An…

  • Silica Gel Case Study

    canisters. The method of producing silica gel was patented in 1918 by Walter A. Patrick , a chemical professor at John Hopkins University. 2.2.2 SYNTHESIS OF SILICA GEL 2.2.2. a) USING KAOLIN BY-PRODUCT The synthesis process (D. Brahmia 2014) was carried out in two steps namely, (1)Metasilicate sol preparation and (2) Metasilicate destabilization with acid. In the first step, a mixture of sodium carbonate and sand were heated to 1000°C to form silicate. Sodium silicate formed in…

  • Advantages And Disadvantages Of Graphite

    Graphite, natural or synthetic, is composed of covalently bonded carbon atoms that are crystalline in structure due to Van der Waals attraction of its layered carbon sheets. It has a gray or black color, with thermal and electrical conductivity. With its properties, it can be used in many “industrial applications like in batteries and fuel cells” (Olson 2003). Although graphite has its useful characteristics, its performance is limited due to its large particles’ size resulting to “low aspect…

  • Advantage And Disadvantage Of Graphene

    1. INTRODUCTION Graphene consists of single layer of carbon atoms arranged in a hexagonal lattice. It is the basic structural element of many other forms of carbon, such as graphite, charcoal, carbon nanotubes and fullerenes. In simple terms, graphene, is a thin layer of pure carbon bonded together in a hexagonal honeycomb lattice. It is the thinnest compound known to man, the lightest material known, the strongest compound discovered, the best conductor of heat at room temperature and also the…

  • Summary: Incomplete Carbon Glucose

    CHAPTER 4 RESULTS AND DISCUSSION 4.1 Incomplete Carbon Glucose Preparation for sulfonated solid acid catalyst must undergo a process which is called carbonization or pyrolysis. Glucose is natural organic compounds had been used as starting raw material because it is cheap and less toxic. Carbonization is an important step before the sulfonation process because it will form amorphous carbon composed of small carbon sheets [B] and produced sites for sulfonic group to be attached or…
