Hexavalent Chromium Reduction Using Supported N-Zvi And Metalloporphyrin Matrices, Jonathon Ball

All Theses

Chromium (Cr) can exist in the environment in many valence states ranging from -2 to +6. Hexavalent chromium (Cr(VI) and trivalent chromium (Cr(III) are the most stable forms of Cr and therefore are the most common in the environment. Cr(VI) is very toxic and has been considered a hazardous material and danger to society for many years. One of the main locations of Cr(VI) contamination in the environment is in groundwater aquifers. A simulation of this system coupled with a reduction-precipitation remediation method was utilized. In this research, n-ZVI was used in a supported silica sol-gel matrix by itself and …
