PRECIPITATION EFFECTS ON SOIL CHARACTERISTICS IN TROPICAL RAIN FORESTS OF THE CHOCO BIOGEOGRAPHICAL REGION

Revista Facultad Nacional de Agronomía Medellín, 2016
Average annual precipitation (AAP) is one of the principal environmental factors that regulates processes in terrestrial ecosystems. The effect of AAP on the availability of edaphic nutrients is poorly understood, especially in tropical zones with high ...

Electrodeposition of Zn-Mn alloys from recycling battery leach solutions in the presence of amines [PDF]

, 2010
The recovery of metal ions by electrodeposition from solutions resulting from the lixiviation of spent Zn-MnO2 batteries was studied. It was attempted to optimise the electrodeposition process, the selectivity of ion-separation, the morphologic ...

Recovery of Cs-137 from electric arc furnace dust by lixiviation

Case Studies in Chemical and Environmental Engineering, 2022
An orphan radioactive source of Cs-137 was inadvertently melted in an electric arc furnace, generating large volumes of electric arc furnace dusts contaminated with Cs-137 (137Cs-EAFD). This work proposes the Cs-137 recovery from 137Cs-EAFD by applying a

Thermodynamic Considerations on Gold Dissolution in Different Lixiviants (II)

Revista de Chimie, 2019
The paper presents the main thermodynamic aspects related to the gold dissolution with thiosulphate, thiourea and thiocyanate. The thermodynamic stability of the gold complexes and the reaction mechanisms that ensure the gold dissolution in the most representative lixiviants with potential for use in the gold industry are analyzed. The performances of

Removal efficiency of 137Cs from radioactively contaminated electric arc furnace dust using different solvents

Case Studies in Chemical and Environmental Engineering, 2023
An advertent meltdown of radioactive source during steel smelting generates electric arc furnace dust (EAFD) polluted with 137Cs. The removal efficiency of 137Cs from EAFD was assessed by the lixiviation method using different solvents and at various ...
