Beryllium desorption from minerals and organic ligands over time

Kinetics of copper desorption from soils as affected by different organic ligands

*Corresponding Author Email: [email protected] Tel.: +2 0359 04684; Fax: +2 0359 04684 ABSTRACT: Desorption of Cu and low molecular weight dissolved organics are the primary factors that impact fate and transport of Cu in soils. To improve predictions of the toxicity and threat from Cu contaminated soil, it is critical that time-dependent desorption behavior be understood. In this paper, the...

Sulfate minerals and organic compounds on Mars

Strong evidence for evaporitic sulfate minerals such as gypsum and jarosite has recently been found on Mars. Although organic molecules are often codeposited with terrestrial evaporitic minerals, there have been no systematic investigations of organic components in sulfate minerals. We report here the detection of organic material, including amino acids and their amine degradation products, in ...

Beryllium and Beryllium Compounds

Beryllium (atomic number, 4; relative atomic mass, 9.01) is a metal, which belongs to Group IIA of the Periodic Table. The oxidation state of beryllium compounds is +2. Selected chemical and physical properties of beryllium, beryllium– aluminium and beryllium–copper alloys, and various beryllium compounds can be found in the previous IARC Monograph (IARC, 1993). Beryllium is the lightest of all...
