The phenol coefficient
WebbAnswer: The Phenol coefficient, is now largely of historical interest, although the principles upon which it is based are still used.[1] It is a measure of the bactericidal activity of a chemical compound in relation to phenol. When listed numerically, the figure expressing the disinfecting powe... WebbTo sum up, some researchers have found that the theoretical phenol coefficient of Dettol is 1 (Sharif, 2014), which means that Dettol is more effective than Phenol. Nevertheless, the results obtained in this laboratory with a PC of 5 shows that this detergent is less effective than the Phenol, the reasons for the possible failed were explained previously.

Webb10 apr. 2024 · The direct path coefficient of soil phenol oxidase activity on the species number of invasive plants was obviously greater than that of the activities of soil urease, protease, and peroxidase (Fig. 1). DISCUSSION. Generally, the invasion of numerous invasive plants can affect soil enzyme activities. The phenol coefficient can be defined as: “The number obtained by dividing the degree of dilution of test disinfectant by the degree of dilution of phenol in a certain span of time.” If the number is greater than 1, it means that for given dilution, the test disinfectant is more powerful and can kill germs better than … Visa mer Phenol is an aromatic compound and a carboxylic acid whose formula is C6H6O.

WebbA chemical agent with a phenol coefficient greater than 1.0 is more effective than phenol, such as chloramine, with phenol coefficients of 133 and 100, respectively. Although the phenol coefficient was once a useful measure of effectiveness, it is no longer commonly used because the conditions and organisms used were arbitrarily chosen. WebbA phenol coefficient of 1.0 means that the chemical agent has about the same level of effectiveness as phenol. A chemical agent with a phenol coefficient of less than 1.0 is …
