Jarosites: Formation, Structure, Reactivity and Environmental
نویسندگان
چکیده
Jarosite, beudantite and alunite are members of the supergroup. Minerals like those have been detected in different environments on Earth. These jarosite-type compounds common acid rock drainage sulfate soils, resulting from weathering sulfide ores; they also present bioleaching systems because found cultures iron-oxidizing microorganisms. Jarosite is generated hydrometallurgical circuits, mainly zinc hydrometallurgy. minerals can be used to immobilize elements such as arsenic lead, among others. surface Mars; presence jarosite other sulfates provides evidence for existence water Mars. In this work, an exhaustive review natural formation, synthesis, structure, thermodynamics, reactivity jarosite, included. The capacity jarosites immobilization elements, lead arsenic, information about studies related formation Mars

Computational Investigation of Structure and Reactivity of Methyl Hydrazinecarbodithioate
In this study, we theoretically investigated Methyl hydrazinecarbodithioate by quantum chemical calculations for geometry optimization, vibration frequencies, and electronic structure parameters. The geometry optimization by DFT, ab initio MP2 method and the frequency calculation by DFT method was performed at the highest available Pople style 6-311G++(3df,3pd) basis set level. The semi-emp...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Effect of NaNO2, HNO3 and H2SO4 on the structure and reactivity of gamma-alumina
The influence of NaNO2, HNO3 and H2SO4 on the structure and morphology of gamma-alumina was investigated by XRD, BET, SEM and FT-IR spectroscopy. Selected amounts of NaNO2, HNO3 and H2SO4 were added to a solution of aluminum isopropoxide (as a precursor for the boehmite synthesis). The boehmite samples were calcined at 350 and 600 ℃ to form the semi-crystalline high surface area gamma-Al2O3. Th...
متن کاملMyochrysine Solution Structure and Reactivity
We have determined the framework structure of Myochrysine (disodium gold(I)thiomalate) in the solid state and extremely concentrated aqueous solution, previously. It consists of an open chain polymer with linear gold coordination to two thiolates from the thiomalic acid moieties which bridge between pairs of gold atoms providing an Au-S-Au angle of 95 degrees . The question remained: was this s...
متن کاملHunting for the magnesium(I) species: formation, structure, and reactivity of some donor-free Grignard compounds.
Magnesium bromide radicals have to be prepared as high-temperature molecules and trapped as a metastable solution because a seemingly simple reduction of donor-free Grignard compounds failed. However, the essential role of magnesium(I) species during the formation of Grignard compounds could be demonstrated experimentally.
