Selenium (Se) is both beneficial and toxic to animals, plants, and humans. Consequently, it
is imperative to know its concentration in the environment and to understand the processes …

Worldwide contamination of waters by metals, metalloids, and organometallic pollutants is a
major health issue. In particular, the occurrence of the selenium metalloid at rather high …

Metals in the hydrological cycle represent a very broad subject covering all parts of the
geological cycle. The present version of this book, therefore, would not have been possible …

Removal of Pb2+ and Ni2+ from aqueous solutions by sorption onto natural bentonite was
investigated. Experiments were carried out as a function of particle size, the amount of …

This work compares and models the adsorption of selenium and other anions on a neutral to
alkaline surface (amorphous iron oxyhydroxide) and an acidic surface (manganese dioxide) …

Iron oxides are good adsorbents for uncomplexed metals, some metal-ligand complexes,
and many metal oxyanions. However, the adsorbent properties of these oxides are not fully …

The absorption characteristics of some heavy metals, namely CU (II), Pb (II), Ni (II) and Zn (II)
onto the hydrous activated carbon surface are studied. Carbon type, pH and surface loading …

The adsorption of phosphate and sulfate on goethite is studied individually and in
combination at solution concentrations of phosphate ranging from 10− 8 to 10− 4 M and of …

A new model for the sorption of cations on metal oxides is formulated which allows for a
continuum between surface reactions and precipitation. The model extends the surface …

This primer was originally developed as a companion volume to a short course on trace
metal-sediment chemistry. The purpose of the course was to expose the participants to the …
