2,4-Dichlorophenoxyacetic acid (2,4-D) degradation promoted by nanoparticulate zerovalent iron (nZVI) in aerobic suspensions
(2013-05-30)
Reactive species generated by Fe0 oxidation promoted by O2 (catalyzed or not by ligands) are able to degrade contaminant compounds like the herbicide 2,4-dichlorophenoxyacetic acid. The degradation of 2,4-D was influenced ...

Bioleaching Model of a Copper-Sulfide Ore Bed in Heap and Dump Configurations
(1998-08)
A two-dimensional (2-D) model for a heap or dump bioleaching of a copper ore containing mainly
chalcocite and pyrite has been developed. The rate of the mineral sulfide dissolution was related to
the rate of oxidation ...
Cyclodextrine-nanoencapsulation of niclosamide: Water solubility and meaningful enhancement of visible-light—Mediated sensitized photodegradation of the drug
(Elsevier Science Sa, 2017-11)
A kinetic and mechanistic study of the daylight-mediated photooxidation of the multifunctional drug Niclosamide (NSD) was carried out in aqueous solutions. NSD is a frequent contaminant suspended in natural waters. The ...
Determination of electrochemical parameters and corrosion rate for carbon steel in un-buffered sodium chloride solutions using a superposition model
(2007)
Corrosion of carbon steel in un-buffered NaCl solutions was studied applying linear potential sweep technique to a rotating disk electrode. Current-potential curves were obtained from linear potential sweep at a rate of 1 ...
Two-dimensional dynamic model of a copper sulphide ore bed
(ELSEVIER, 2003-10)
A two-dimensional dynamic model for bioleaching of secondary copper minerals from a pile has been developed. In the model. aeration of the pile is considered to be due to natural convection caused by the density gradient ...
