Activated carbon

Activated carbon is a form of carbon that has treated in order to give it small pores, with lower volume, this increases the surface area accessible for adsorption. Adsorption is a procedure where solids are used for taking a soluble contaminate out of water. In this procedure active carbon is the solid that has been mentioned. The reason activated carbon is such a good filter is because of the huge surface area (between 300-2000m2/g), this is because surface area is proportional to adsorption capacity. Several factors can have an effect on activated carbon one factor includes temperature when the temperature increases the adsorption capacity decreases. Pour size is very important in activated carbon the pours have substantial adsorption forces…

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…

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…

The ammonia color detector tube will be broken just under the ceiling of the third floor. In addition, the ladder will provide a vantage point for measuring the ammonia gas receding from the colony. The carbon monoxide color detector tube will be broken within ten feet of the colony from the third floor. This will give a reading of the carbon monoxide levels that the colony is exposed to on a day to day basis. In the meantime, a Hobo Meter will be activated amidst the other readings taking…

 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…

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…

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…

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…

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…
