Degradation of emergent contaminants by UV, UV/H2O2 and neutral photo-Fenton at pilot scale in a domestic wastewater treatment plant.
This study focuses on the removal of 22 selected micropollutants in an effluent from a municipal wastewater treatment plant (MWTP) at pilot scale. A reactor of 37 L with five low pressure mercuryExpand

Catalysis with supported palladium metal, selectivity in the hydrogenation of CC, CO and CN bonds, from chemo- to enantioselectivity
Abstract The selectivity characteristics of Pd catalysts in heterogeneous hydrogenations are discussed, especially the stereochemical issues in the reduction of CC, CO and CN bonds. SpecialExpand
