Toxic Industrial Chemical Removal by Isostructural Metal-Organic Frameworks

Abstract

Cobalt, magnesium nickel, and zinc MOF-74 analogs have been synthesized, characterized, and evaluated as novel adsorbent materials for the removal of toxic industrial chemicals. Nitrogen porosity. X-ray diffraction, and water adsorption data are presented in addition to breakthrough curves for ammonia, octane, cyanogen chloride, and sulfur dioxide. The materials were evaluated in humid and dry conditions. The results show that in an isostructural environment changes in the metal contained in the structural building unit of MOF-74 materials have a significant effect on the resulting dynamic breakthrough capacity. In general, cobalt and magnesium MOF-74 materials perform better than either nickel or zinc MOF-74 in dry and humid conditions; however, in most cases, humidity significantly decreases the performance of all the materials studied.
