  • Phenol Concentration Lab Report

    1403 Words  | 6 Pages

    phenol concentration provides an important driving force to overcome all mass transfer limitations of phenol between the aqueous and sorbent phases. Therefore a higher opening phenol concentration will enrich the biosorption process. The increase in sorption capacity of bacterial strain with an increase in the initial phenol concentration might be due to a higher probability of collision between the phenol molecules and biosorbent. With increase in phenol concentration from 100 to 500 mg/L, the percentage

  • Propionic Acid Research Paper

    1629 Words  | 7 Pages

    The method of production and separation of propionic acid is a complex one and over the course of years, various methods have been explored, invented and commercialized. The earliest known work performed in the separation of propionic acid dates back to the early 1900’s. To make sure that the work that will be done for this particular project is in a direction that is not explored before, extensive research papers have been read-both form the past and the most recent as well, websites have been searched

  • Advantages And Disadvantages Of Co2 Sequestration

    803 Words  | 4 Pages

    biological strategies. . One physical method to capture CO2 is in deep oceans, gas wells and aquifers. Physical CO2 sequestration has some disadvantages of high cost and capturing and storage is also very expensive process. Another method is chemical sorption of CO2power plants. Plants can naturally capture the carbon dioxide and use it for photosynthesis by biological fixation. Terrestrial plants capture more amount of carbon dioxide but the actual atmospheric carbon dioxide is just 0.036%, so it is

  • Essay On Self Ligating Bracket

    905 Words  | 4 Pages

    the polymeric structure or filler content, and surface roughness play a decisive role in the extent of discoloration caused by diverse substances. The amount of colour change is influenced by a number of factors such as oral hygiene, water sorption, and incomplete polymerization. As to the color stability of ceramic brackets, it has been reported that both polycrystalline and monocrystalline ceramic brackets resist staining or discoloration from the chemical substance likely to be encountered

  • Desalination Research Paper

    974 Words  | 4 Pages

    Desalination is a common solution to supply fresh water in many regions of the world where face with water scarcity [1]. Water scarcity is one of the most important problems in many parts of Iran and desalination of saline water (sea and brackish water) is the monopolized solution to provide water for drinking, agricultural and industrial purposes [2]. The majority of water resource does not satisfy to the desirable levels of chemical properties, such as hardness, nitrate contamination, heavy metals

  • White Phosphorus Research Paper

    Local pollution description General physical and chemical properties of Phosphorus What is the definition of Phosphorus? It is a highly reactive, poisonous, non-metallic element occurring naturally in phosphates, especially apatite. It exists in three allotropic forms, white, red and black. Physical Properties White phosphorous is white, waxy solid, giving off a greenish-white glow in the dark. It is spontaneously flammable when exposed to air and is deadly poison

    excess is separated from the amalgam just by hand pressing, in most of the cases (Maurice-Bourgoin et al., 1997). Nevertheless, Veiga et al., (2006) explains that mercury wetting of gold is not actually a real alloying process, but a “moderate deep sorption which involves some interpenetration of the two elements”. Since mercury's surface tension is less than gold but greater than water, “it adsorbs onto the surface of gold particles. In addition, mercury acts as a dense medium; gold sinks into the

  • Essay On Vanadium

    1459 Words  | 6 Pages

    The Element Vanadium and its Uses Vanadium was discovered by Andrés Manuel del Rio, a Mexican chemist, in 1801. Rio sent samples of vanadium ore and a letter describing his methods to the Institute de France in Paris, France, for analysis and confirmation. Unfortunately for Rio, his letter was lost in a shipwreck and the Institute only received his samples, which contained a brief note describing how much this new element, which Rio had named erythronium, resembled chromium. Rio withdrew his claim

  • Fibroblast Research Paper

    2301 Words  | 10 Pages

    Fibroblast The fibroblast is the large cell type of the dermis. These cells are responcible for the formation of procollagen and elastic fibers. Procollagen is terminally cleaved by proteolytic enzymes into collagen which aggregates and turned into cross-linked. These tightly cross-linked collagen fibers allow tensile strength and resistance to shear and other mechanical forces.(9,10) Collagen makes up 70% of the weight of the dermis, primarily Type I (85% of the total collagen) and Type III (15%
