Mobility of heavy metals in soils amended with sewage sludge
(Agricultural Institute of Canada, 2001)
Artículo / Artikulua,
Sewage sludges added to arable land can improve soil fertility and physical properties. However, the concentrations of heavy metals commonly found in sludges limits their application to soil. The purpose of this paper is ...
Bioavailability of heavy metals in soils amended with sewage sludge
(Agricultural Institute of Canada, 2002)
Artículo / Artikulua,
The recycling of sewage sludge to agricultural land results in the slow accumulation of potentially toxic heavy metals in soils. A greenhouse experiment was conducted to determine the bioavailability of Cu, Ni, Pb and ...
Application of gold complexes in the development of sensors for volatile organic compounds
(World Gold Council, 2007)
Artículo / Artikulua,
Two different kinds of sensors have been developed by using the same kind of vapochromic complexes. The vapochromic materials [Au2Ag2(C6F5)(4)L-2](n) have different colours depending on the ligand L. These materials change, ...
Influence of the power supply on the energy efficiency of an alkaline water electrolyser
