The colors present in the effluent from dyeing and textile plants are one of the most dangerous sources of environmental pollution due to their toxicity and carcinogenesis. Dye removal is, therefore, necessary to prevent their discharge into the environment. A number of methods are available for dye removal from industrial effluents, among which Fenton/Ultrasonic oxidation process is an effective one due to its high efficiency in color removal. The objective of this pilot-scale experimental study was to investigate the operational parameters involved in the removal of Reactive Red 2 dye (RR2) using the Fenton/Ultrasonic process and its efficiency. Theeffects of pH, H2O2, and Fe2+ were evaluated using an ultrasonic reactor at 40 KHz with a power of 100W. Once the parameters had been optimized, the effects of temperature, mixing speed, and different dye concentrations on the Fenton/Ultrasonic process efficiency were measured. The optimal parameters of pH, hydrogen peroxide, and ferrous ion concentration in the were determined to be 3, 2, and 0.2 mmole, respectively, in 45 minutes so that a removal efficiency of 98.91% was obtained for an optimum hydrogen peroxide to ferrous ion ratio of 10. The results indicated that the Fenton process has a good performance in the removal of Reactive Red 2.

DSpace is a platform that allows you to capture items in any format – in text, video, audio, and data. It distributes it over the web. It indexes your work, so users can search and retrieve your items. It preserves your digital work over the long term.<br />DSpace provides a way to manage your research materials and publications in a professionally maintained repository to give them greater visibility and accessibility over time.<br />DSpace is typically used as an institutional repository. It has three main roles:<br />1. Facilitate the capture and ingest of materials, including metadata about the materials<br />2. Facilitate easy access to the materials, both by listing and searching<br />3. Facilitate the long term preservation of the materials<br />• Getting your research results out quickly, to a worldwide audience <br />• Reaching a worldwide audience through exposure to search engines such as Google <br />• Storing reusable teaching materials that you can use with course management systems <br />• Archiving and distributing material you would currently put on your personal website <br />• Storing examples of students’ projects (with the students’ permission) <br />• Showcasing students’ theses (again with permission) <br />• Keeping track of your own publications/bibliography <br />• Having a persistent network identifier for your work, that never changes or breaks <br />• No more page charges for images. You can point to your images’ persistent identifiers in your published articles.
