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 ...
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 ...
Kinetics of the acid-catalyzed hydrolysis of tetraethoxysilane (TEOS) by 29Si NMR spectroscopy and mathematical modeling
(Springer, 2018)
Artículo / Artikulua,
Tetraethoxysilane (TEOS) is widely used to synthesize siliceous material by the sol–gel process. However, there is still some
disagreement about the nature of the limiting step in the hydrolysis and condensation reactions. ...
Fiber optic sensors based on hybrid phenyl-silica xerogel films to detect n-hexane: determination of the isosteric enthalpy of adsorption
(Beilstein-Institut, 2017)
info:eu-repo/semantics/article,
We investigated the response of three fiber optic sensing elements prepared at pH 10 from phenyltriethoxysilane (PhTEOS) and
tetraethylsilane (TEOS) mixtures with 30, 40, and 50% PhTEOS in the silicon precursor mixture. ...
