1. 1. Spatial analysis of arsenic and fluoride mobilization in groundwater around Mount Meru, northern Tanzania

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Henriette Nishimwe; [2023]
   Keywords : Arsenic; Fluoride; Groundwater; Mobilization; Mount Meru; Geochemical and Spatial Modelling; Arsenic; Fluoride; Groundwater; Mobilization; Mount Meru; Geochemical and Spatial Modelling;

   Abstract : In Tanzania, approximately 76% of the drinking water supplies is dependent on groundwater sources. However, the groundwater in north Tanzania is susceptible to contamination by arsenic and fluoride. This study examines the spatial analysis of arsenic and fluoride mobilization in groundwater around Mount Meru, located in northern Tanzania. READ MORE

3. 2. Fluoride removal by low-cost adsorbents

   University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

   Author : Fredrik Bernheim; [2022]
   Keywords : Fluoride; calcium; adsorption; surface precipitation; pH; AOD-slag; ion chromatography; MP-AES; isotherms; Langmuir; Freundlich; Sips.;

   Abstract : Fluoride, the most abundant form of fluorine, is an ion released into the environment, mainly via anthropogenic sources and erosion of mineral rocks. Although the element is well known for its health benefits on teeth and bones, it can as well be a harmful pollutant. READ MORE

4. 3. Acid neutralization using steel slags : Adsorption of fluorides in solutions using AOD slags

   University essay from KTH/Materialvetenskap

   Author : Jesper Larsson; [2015]
   Keywords : acid neutralization; AOD slag; fluoride adsorption; syraneutralisering; AOD slagg; fluoradsorption;

   Abstract : Surface treatment processes of stainless steel, such as pickling, produces acidic waste water consisting of Na⁺, Cl⁻, F⁻, NO⁻3, SO42-, PO43-, Fe3+, Cr6+ and Ni2+. At Sandvik ABs steel works in Sandviken, this waste water is treated and neutralized using slaked lime before being released into the lake Storsjön. READ MORE

5. 4. Removal of Arsenic in Ground Water from Northern Burkina Faso through Adsorption with Granular Ferric Hydroxide : A SIDA Minor Field Study at the Department of Chemistry, University of Ouagadougou

   University essay from Uppsala universitet/Luft-, vatten- och landskapslära

   Author : Hannes Öckerman; Emma Lundin; [2013]
   Keywords : Burkina Faso; arsenic; Granular Ferric Hydroxide; adsorption; column test; drinking water; ground water; self-regeneration;

   Abstract : The need of making arsenic contaminated ground water potable is urgent in parts of Burkina Faso. An implementation of a treatment design using Granular Ferric Hydroxide (GFH) is under development. Water from a tube-well in Lilgomdé, Yatenga province, Burkina Faso, has been treated with the adsorbent GFH through column experiments. READ MORE
