optimal binding for bovine serum albumin and phenol red because they have very low percent bound (refer to table 1)‚ mostly is the free phenol red. Therefore it matches with the prediction. Moreover‚ there were 2 peaks presented when graphing. Based on the order of elution‚ the first peak is the bound complex of BSA-PR. According to the data in table 1‚ the percent bound of BSA-PR was 61.65%. It is not 100% bound‚ so the second peak is the free phenol red. It is the same with pH6‚ pH8‚ and pH 10

adding a fixed amount of phenol together with some methyl red indicator. The bromine produced during the reaction reacts very rapidly with phenol. Once all the phenol is consumed‚ any further bromine bleaches the indicator immediately. So‚ the time for the reaction to proceed to a given point may be determined.

degradation of phenol has been tested primarily with titanium dioxide (TiO2) either alone or in combination with other materials. In this work‚ Mg/Al hydrotalcites prepared by two methods using inorganic (HC) or organic (HS) chemical reagents‚ along with mixed oxides produced by calcination of these products (HCC and HSC) were mixed with titanium isopropoxide to obtain hydroxide-TiO2 compounds (HCC-TiO2 and HSC-TiO2) to test their photocatalytic activity compared with solutions of 10 mg/L phenol (120 min

_______ ABSTRACT---- Phenol is used as a starting material in the preparation of wood varnish. In this work efforts were made to substitute phenol from tannins extracted from the stem bark of Khaya senegalensis to produce wood vanish and assessed its quality. An extract with a Stiasny Number of 87.88 % and extractable phenols of 2.82 mg/kg was used to synthesize a phenol-formaldehyde called tannin-formaldeyde. Properties of this resin were compared with that of phenol-formaldehyde resin synthesized

"model organisms" for studying problems in genetics and molecular biology. The lactophenol blue staining or known as lacto phenol cotton blue (LPCB) wet mount preparation is the most widely used method of staining and observing fungi and is simple to prepare. The preparation has three components: phenol‚ which will kill any live organisms. The high concentration of the phenol deactivates lytic cellular enzymes thus the cells do not lyse.

extracting Escherichia coli and Enterococcus spp. bacterial DNA from human faecal samples: an in-house phenol/chloroform extraction‚ and two commercially available kits‚ ExtractMaster (Epicentre Biotechnologies) and UltraClean (Mo Bio Laboratories) faecal DNA extraction kits. Real-time PCR using the standard curve method was used to quantify the level of bacterial DNA extracted from ten faecal samples. The phenol/chloroform method required an additional dilution step before DNA could be amplified by real-time

Arenes The aromatic hydrocarbons also have the name arenes. They contain in their molecule one or more cycles made up from 6 carbon atoms. When the molecule is formed out of a single cycle‚ the hydrocarbons are mono nucleuses; when the molecule contains more than one cycle‚ the hydrocarbons are poly nucleuses. The simplest aromatic hydrocarbon‚ benzene‚ is compound out of just one such cycle; its formula is C6H6. The representation of benzene through a cycle of 6 carbon atoms with 3 double bounds

Separation of a Carboxylic Acid from a Neutral Compound by Extraction Reference: Smith‚ Chapter 2 (Acids and Bases) Introduction Carboxylic acids and phenols are two families of organic compounds that contain carbon‚ hydrogen and oxygen‚ and also react with water to yield an excess of hydronium ions over hydroxide ions. Pure water has a pH of 7‚ which means it has a hydronium ion concentration‚ [H3O+] of 10-7 M (M = molarity‚ moles/Liter). The hydronium ions in pure water come from the self-ionization
