  author={Wolfgang H. H{\"o}ll and Zha Xuan and K. Hagen},
The selective elimination of traces of heavy metals from raw waters of the drinking water supply by means of commercially available weakly basic anion exchangers has been investigated. Target species were heavy metal cations (of Hg, Cd, Zn, Ni, Cu, Pb) and chromate (Cr(VI)) anions. In the laboratory investigations, suitable anion exchangers were indentified. The phenol formaldehyde-based resin Duolite A7 revealed optimum properties for sorption of practically all heavy metal cations. Acrylic… 
Deep Treatment of Copper Plant Waste Water Streams with Water Recycling
Reducing the negative environmental impact and securing the efficient use of water resources are key factors in the mining-metallurgical industry. At the enterprises of non-ferrous metallurgy the

Elimination of cadmium trace contaminations from drinking water.
The respective elimination of cadmium from pure solutions and spiked natural water and the regeneration of the exhausted exchanger has been investigated and the results demonstrate a very efficient elimination.
Sorption of Heavy Metals onto Selective Ion-Exchange Resins with Aminophosphonate Functional Groups
The ion-exchange equilibria for the exchange of heavy metal ions (Cu2+, Ni2+, Cd2+, Zn2+, and Co2+) and of Ca2+, Na+, and NH4+ ions by two commercially available chelating ion-exchange resins with
Speciation of mercury in natural waters by capillary gas chromatography with a microwave-induced plasma emission detector following preconcentration using a dithiocarbamate resin microcolumn installed in a closed flow injection system
A method for the simultaneous determination of mercury species at sub-ng l–1 levels in natural waters is described. The detection limits are 0.05 ng l–1 for methyl- and ethylmercury and 0.15 ng l–1
The binding of heavy metals to algal surfaces
Abstract Biological particles can profoundly influence the distribution of heavy metals in natural waters because the functional groups on the cell surfaces are able to bind metal ions. The
Elimination von Schwermetallsalzen aus Wässern durch Adsorption an schwach basischen Anionenaustauschern
Commercially available weak base anion exchange resins can successfully be applied to eliminate heavy metal salts from aqueous solutions. The sorption of heavy metal species is caused by the LEWIS
Developments in the speciation of mercury in natural waters
Abstract Information on mercury and its environmentally significant forms (species) which frequently occur in natural water samples is presented. Compartments of the natural environment considered

The surface complexation model as previously applied to pure anion and pure cation exchange equilibria has been extended to the description of the amphotheric sorption of inorganic ions onto activated alumina to predict the equilibrium of multicomponent systems with excellent accuracy.
Natural and antropogenic enrichments of trace metals in peat profiles
Abstract Samples of mosses, peats, lake sediments and clays were collected from 35 Canadian peatlands and analyzed for Cr, Cu, Fe, Mn, Ni, Pb, U, V and Zn. The average composition of the analyzed
Prediction of multicomponent adsorption equilibria in background mixtures of unknown composition
Abstract In the past, most predictive mathematical modeling work has focused on mixtures of known composition. Unfortunately, drinking water and wastewater contain many competing organic solutes and
Application of the surface complex formation model to exchange equilibria on ion exchange resins Part III: Anion exchangers
Abstract The surface complexation theory considers the sorption of ions as a local equilibrium reaction, which is caused by the amphoteric behaviour of the surface. Application of this theory to
