Methylene Blue Dye Test Strips for Qualitative Detection of Hydroxyl Radicals
- Detailed Technology Description
- Description of Technology Michigan State University’s invention is a method for indicating the presence of hydroxyl radicals in an aqueous solution. The method uses a simple procedure requiring inexpensive materials, without the addition of competitive probe chemicals that potentially can interfere with the reaction. Mythylene blue dye qualitatively indicates the presence of hydroxyl radicals by visible, distinct bleaching of the blue dye on a paper test strip. A lack of bleaching indicates the absence of hydroxyl radicals in the sample. Key BenefitsProvides a rapid, qualitative, visual means of indicating the presence of hydroxyl radicalsSimple and inexpensiveAvoids the use of chemical probes, which are needed for previous methodsCould be applied to remediation of organic and solvent wastes, as well as wastewater treatment Applications The invention can be used to monitor the progress of in situ chemical oxidation of chlorinated solvents at clean-up sites, as well as checking for wastewater and effluent at treatment sites.
