Book excerpt: Academic Paper from the year 2019 in the subject Chemistry - Analytical Chemistry, grade: A, , language: English, abstract: This text is focussing on the effectiveness of oxidizing reagents in removal of blood stains. Adjustments, amendments, and concealing of the crime evidence have resulted in an increment in the world’s crime rate. One such recurring hindrance can be seen with the most vital forms of evidence; bloodstains. Bloodstains are considered to be one of the most difficult stains to remove and even after cleaning them off the clothes through the detergents available in the market, there are some colored traces left which do not disappear completely and can be detected. Forensic scientists use luminol to detect bloodstains which when reacted with iron in blood stains exhibit chemiluminescence. This led to thinking of to what extent were these criminals able to manage the escape by washing the stains and hinder the evidence. After researching about the detergents from journals and websites like "The Science of Stain Removal, Study of Oxyper- H2O2, and Study of sodium perborate" and also studying the effect of various compounds present in them, it was found out that the active oxygen reagents were the sources through which bloodstain removal was possible. This helped in framing a research idea: To what extent does the change in mass of the oxidizing reagent, sodium perborate, sodium percarbonate and hydrogen peroxide found in detergents is effective in removing bloodstains, measured by spectrophotometric analysis of change in chemiluminescence intensity of luminol due to the oxidation of ferrous to ferric ions in stock solution containing oxidizing agents and iron solution imitating blood at room temperature (30°C)? In this essay, the correlation between the removal of the stains and the extent to which it depends on the amount of reagent was measured. The decrease in chemiluminescence signifies the extent to which the stains are removed. On this basis, the cleansing action of various oxidizing agents like hydrogen peroxide, sodium perborate, and sodium percarbonate was compared. Seeing the competence of the strongest oxidizing reagent, it can be considered that this research will be useful for forensic science departments to detect the extent to which evidence was tried to be concealed as all the oxidizing agents contain H2O2 and even after washing the clothes, some content of H2O2 is left. It will also be valuable for the detergent manufacturers because, through this research, they will opt for a better oxidizing agent to yield a better cleansing action.

Book Synopsis Hydrogen Peroxide Health Benefits and Uses by : Barbara Moore
Download or read book Hydrogen Peroxide Health Benefits and Uses written by Barbara Moore and published by Speedy Publishing LLC. This book was released on 2013-06-06 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydrogen peroxide or better known as H2O2 is a very common compound that is used to clean and disinfect wounds. It is coupled with betadine solution which cleans wounds and reduces the risk of infection. But what most of us don't know is that the lowly hydrogen peroxide may also be used in other ways and this is due to the efficient properties of this compound. Hydrogen peroxide appears clear and slightly viscous compared to water in room temperature. This compound is available in opaque plastic bottles and is sold in most drug stores or chemists.

Available in PDF, EPUB and Kindle. Book excerpt: This book gives the reader an introduction to the field of surfactants in solution as well as polymers in solution. Starting with an introduction to surfactants the book then discusses their environmental and health aspects. Chapter 3 looks at fundamental forces in surface and colloid chemistry. Chapter 4 covers self-assembly and 5 phase diagrams. Chapter 6 reviews advanced self-assembly while chapter 7 looks at complex behaviour. Chapters 8 to 10 cover polymer adsorption at solid surfaces, polymers in solution and surface active polymers, respectively. Chapters 11 and 12 discuss adsorption and surface and interfacial tension, while Chapters 13- 16 deal with mixed surfactant systems. Chapter 17, 18 and 19 address microemulsions, colloidal stability and the rheology of polymer and surfactant solutions. Wetting and wetting agents, hydrophobization and hydrophobizing agents, solid dispersions, surfactant assemblies, foaming, emulsions and emulsifiers and microemulsions for soil and oil removal complete the coverage in chapters 20-25.
