Provision of clean and efficient water remediation around the world is becoming an increasingly critical issue. There are several methods utilized for water remediation, however, most are costly and often reach inefficacious results. Cost-effective metal-organic frameworks (MOFs), which are 3-dimensional arrays consisting of metal ions or clusters coordinated to organic linkers, exhibit large surface areas and high tunability. These characteristics make MOFs excellent at guest-host interactions, and potentially suitable candidates for water remediation and antimicrobial activity. The work presented focus on the development, characterization, and application of post-synthetically reduced MOF-199 composite polymers for water filtration. An analysis was done on antimicrobial behavior by the MOF towards the gram-negative bacteria, E. coli. The antimicrobial behavior was studied using Kirby Bauer experiments as well as light scattering techniques using a UV/Vis spectrometer. Characterization of the composite materials was done using IR spectroscopy, and material stability and copper leaching were evaluated through atomic absorption spectroscopy. To test adsorption/desorption properties and study those mechanisms, methylene blue and methyl blue were used through batch studies.
