  1. 1. INVESTIGATION OF PHOSPHORUS SORPTION BY SEDIMENT DERIVED BIOCHAR - A LITERATURE REVIEW

    University essay from Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Author : Christina Henricson; [2023]
    Keywords : ;

    Abstract : As excess phosphorus in water bodies causes eutrophication, biochar can be used as an adsorbent to remove phosphorus from water, thus increasing the circularity of phosphorus in the society. This literature review is a summary of recent research on optimised uptake of phosphorus by sediment derived biochar. READ MORE

  2. 2. The role of bed sediments for sorption of phosphorus in remediated ditches in Sweden

    University essay from SLU/Dept. of Soil and Environment

    Author : Linus Holgersson; [2022]
    Keywords : Phosphorus; Two-stage ditch; Equilibrium phosphate concentration; Phosphorus retention; Eutrophication; Soluble reactive phosphorus;

    Abstract : Human activities have increased nutrient losses to agricultural ditches and streams, including phosphorus. Phosphorus leakage leads to a worsening of water quality in downstream ecosystems, including lakes and seas. In addition, higher phosphorus concentrations lead to eutrophication, which negatively affects aquatic systems. READ MORE

  3. 3. Sorption of Stormwater Pollutants for Five Material Mixtures: A batch Equlibrium Study

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Fredrik Rydholm; [2021]
    Keywords : Sorption; Swale; Metals; Phosphorus; Treatment; Batch equilibrium test; isoterms; Low-cost material;

    Abstract : Blue-green infrastructure have been more lucrative during the last 30 years, since urbanizationbrings more impervious surfaces that increases stormwater runoff volumes. Amongst thedifferent blue-green infrastructures there are e.g., constructed wetlands and swales. READ MORE

  4. 4. Phosphorus speciation across elevation and vegetation in soils of the subarctic tundra : A solution 31P NMR approach

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Johannes Krohn; [2017]
    Keywords : Climate warming; arctic ecosystems; tundra; phosphorus; Solution 31P NMR;

    Abstract : In tundra, phosphorus (P) is an important macronutrient for plants and microorganisms. A major fraction of P exists as organic compounds in the topsoil which can be mineralized to bioavailable inorganic P. READ MORE

  5. 5. PILCs for trapping phosphorus in a heavy duty engine exhaust system : An experimental evaluation of the phosphorus sorption capability of different clay materials

    University essay from Uppsala universitet/Strukturkemi

    Author : Anders Kvarned; [2016]
    Keywords : PILC; PCH; phosphorus sorption; exhaust treatment; catalyst poisoning;

    Abstract : In order to fulfil the requirements in the EURO VI standard, regulating emissions from heavy duty vehicles, the exhaust aftertreatment system needs to maintain its efficiency for at least seven years or 700 000 km. In diesel applications the diesel oxidation catalyst (DOC) is located closest to the engine and is thus the most vulnerable to poisoning contaminants, such as phosphorus originating from fuel and oil additives, which deactivates the catalyst.
