Sorption Of Cr(Iii) And Cr(Vi) To High And Low Pressure Synthetic Nano-Magnetite (Fe3o4)Particles, Jason Parsons, Jeffrey Hernandez, Christina M. Gonzalez, J. L. Gardea-Torresdey
Chemistry Faculty Publications and Presentations
The binding of Cr(III) and Cr(VI) to synthetic nano-magnetie particles synthesized under open vessel conditions and a microwave assisted hydrothermal synthesis techniques was investigated. Batch studies showed that the binding of both the Cr(III) and Cr(VI) bound to the nano-materials in a pH dependent manner. The Cr(III) maximized at binding at pH 4 and 100% binding. Similarly, the Cr(VI) ions showed a maximum binding of 100% at pH 4. The data from the time dependency studies showed for the most part the majority of the binding occurred within the first 5 minutes of contact with the nanomaterial and remained constant …
