Hillary Korir,Klaus Mueller,L. Korir,J. Kubai,E. Wanja,N. Wanjiku,J. Waweru,Michael J. Mattle,Lars Osterwalder,C. Annette Johnson +9 more
TL;DR: In this paper, the first laboratory results and field testing of a new fluoride removal technology, based on a combination of bone char and calcium-phosphate proteins, were presented.
Journal ArticleDOI
Arsenic and Other Geogenic Contaminants in Groundwater - A Global Challenge.
TL;DR: The geochemistry and occurrence of arsenic and fluoride in groundwater and on the development of global and regional risk maps that help alert governments and water providers to take appropriate mitigation measures for the provision of safe drinking water are reported on.
Journal ArticleDOI
Strontium hydroxyapatite and strontium carbonate as templates for the precipitation of calcium-phosphates in the absence and presence of fluoride
Vanessa Sternitzke,Vanessa Sternitzke,Markus Janousch,Michèle B. Heeb,Michèle B. Heeb,Janet G. Hering,Janet G. Hering,C. Annette Johnson +7 more
TL;DR: In this paper, Strontium hyclroxyapariLe (Sr-10(PO4)(6)(OH)(2) or SrHAP) and strontium carbonate(SrCO3) were used as calcium free seed templates in precipitation experiments conducted with varying initial calcium-Lophosphate (Ca/P) or calcium-Lo-phosphaLe-lo-fluoride (ca/P/F) ratios.
Book ChapterDOI
Heavy Metal Binding Mechanisms in Cement-Based Waste Materials
TL;DR: In this article, field and laboratory experiments were carried out to elucidate the geochemical and hydrological mechanisms that are important to understand the binding mechanisms of heavy metals in landfills with cement-based waste materials.
