EXPERIMENT 5: CHROMATOGRAPHY Abstract Paper Chromatography uses a chromatogram paper as its stationary phase and the solvent as the mobile phase. Retention factor is the ratio of the distance travelled by the sample to the distance travelled by the solvent. This experiment aims to separate organic compounds‚ to compute Rf values and to identify unknown compounds using Rf values. The ten samples underwent paper chromatography to determine the components of the unknown sample. The mobile phase allowed

Synopsis This experiment was carried out with the objective to study the effects of homogenisation on the droplet size of the dispersed phase of an emulsion of a two stage homogeniser. The results collected shows that the pressure of the homogenisation process will affect the temperature‚ height of separation and fat globule distribution of the coconut milk. The process of homogenisation involves pressure forcing the coconut milk through a membrane to make the fat particles small enough to mix together

Abstract: The optical and photocatalytic properties of Nb2O5 sculptured thin films (STF) are investigated. Films are synthesized via sol- gel route using spin coating technique. The sol is prepared from niobium ethoxide. The films are prepared at different rpm to tailor the thickness. The structures of the films are investigated through XRD measurements. Refractive index‚ extinction coefficient and thickness of the films are determined from Variable Angle Spectroscopic Ellipsometery. The absorbance

Running head: LAB 5: INVESTIGATING AN ENZYME-CATALYZED REACTION Lab 5: Investigating an Enzyme-Catalyzed Reaction September 24‚ 2014 Principles of Biology 120.601 Mrs. Annemarie Duncan Abstract: (Burmania) This experiment was performed in order to examine ways in which a potato catalase enzyme reacts to various assays with differing variables. To do so a baseline assay (undiluted extract and room temperature H2O2) was used within the experiment with only one other variable changed in
Premium Catalase Chemical reaction Catalysis
is an enzyme that brings about the reaction by which hydrogen peroxide is decomposed to water and oxygen (Encyclopedia Britannica). The chemical reaction is shown as 2H2O2 = 2H2O + O2 (Keilin and Hartree 397). The reaction involves primarily the adsorption of hydrogen peroxide at the catalase surface. The decomposition of hydrogen peroxide by catalase is regarded as involving

MODELING LEACHATE MIGRATION FROM A LANDFILL December‚ 2003 1 INTRODUCTION A two-dimensional‚ steady state transport modeling using MODFLOW/CTRAN was carried out following the particle tracking calculations to simulate potential contamination for leachate migration from Gibraltar landfill. Gibraltar landfill was a disposal waste site in Bogotá (Colombia) until 1988. The site presented problems related to contamination for leachate migration after its closure‚ since the operation

Biotechnology In environment Clean up Process - APPSC G1 Mains - Paper 4 - Section 2 - Unit 3 The term "Environment" is defined as our surroundings which includes the abiotic component (the non living) and biotic component (the living) around us. The abiotic environment includes water‚ air and soil while the biotic environment consists of all living organisms – plants‚ animals and microorganisms. Environmental pollution broadly refers to the presence of undesirable substances in the environment
