This reaction is connected to high overpotentials, which are in Zn electrowinning about 800 mV, or 20–25% of the total cell voltage, and with that an equal amount of the total electrical energy1. Many attempts have been made to reduce the overpotential by introducing better catalysts. The main anode systems are nowadays all lead based1, which offer the best cost:value ratio for most of the indu...
Contamination of Elbe River (Germany) sediments with dioxin-like toxicants was investigated following the 500-year flood (flood that statistically occurs once in 500 years) of 2002. It was hypothesized that large amounts of particulate matter from river beds and associated dioxin-like toxicants were mobilized and transported during this flood event. The investigation focused on polychlorinated ...
The discharge of potentially toxic trace metals into the environment has become a global problem. As a result of industrial activities and technological development, the amount of heavy metal ions discharged into streams and rivers by industrial and municipal waste-water have been increasing. In addition to natural sources of heavy metals (i.e. geologic weathering, volcanic activity, and animal...
