New technologies in catalysis using base metals*
Formation of C–C, C–N, and C–H bonds using three heterogeneous catalysts in the form of nickel-in-charcoal (Ni/C), nickel-on-graphite (Ni/Cg), and copper-in-charcoal (Cu/C) are described.
متن کاملMetals Removal Technologies for Stormwater
This study, on innovative methods for the capture of metals from stormwater, focused on two major areas of investigation: media filters and swales. The test water for both the filters and the swales was a stormwater which was collected from a parking lot during wet weather events. The characterization of the stormwater showed that the most prevalent metals detected in the runoff were iron, zinc...
متن کاملMetals Removal Technologies for Stormwater: Filtration
This study, sponsored by the Water Environment Research Foundation, focused on innovative methods for the capture of metals from stormwater. The two areas of focus were media filters and swales. This paper will focus on the filter studies. Twelve media were chosen for initial evaluation. Equilibrium and kinetic studies were formed on these media to assess their performance in capturing metals f...
