Functionalized sepiolite for heavy metal ions adsorption

open access: yesDesalination, 2008
Abstract Surface modification of clays has become increasingly important due to the practical applications of clays such as fillers and adsorbents. The surface modification of sepiolite with [3-(2-aminoethylamino)propyl]trimethoxysilane has been employed. The modified sepiolite surface was investigated by FTIR, XRD and DTA/TG analysis.

The Relationship between pH and Heavy Metal Ion Sorption by Algal Biomass

open access: yesAdsorption Science & Technology, 2003
The relationship between pH and heavy metal ion sorption by the biomass of two algal species was studied under controlled experimental conditions. It was observed that increasing heavy metal ion sorption by algal biomass with pH mainly arose from a ...

The migration process and temperature effect of aqueous solutions contaminated by heavy metal ions in unsaturated silty soils

open access: yesHeliyon
Adsorption-desorption experiments of three heavy metal ions (i.e., lead, copper, cadmium) in silty soil were carried out at different temperatures, and the microscopic characteristics of silty soil loaded with the three heavy metal ions were analyzed.

Heavy Molecular and Metallic Ions in the Magnetosphere

open access: yesSpace Science Reviews
AbstractObservations and present knowledge of heavy ions with mass ≥ 27 in the magnetosphere are reviewed. There are four ultimate sources of these heavy ions: the solar wind (mainly high charge-state atomic ions), the ionosphere (mainly molecular ions), the atmospheric metal layers that originate ultimately from ablation of meteoroids and possibly ...
