  1. 1. Remediation of per- and polyfluoroalkyl substances (PFAS) in contaminated water by sorption to pine- and spruce bark

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Rebecka Ayranci Dahlberg; [2023]
    Keywords : Per- and polyfluoroalkyl substances; sorption; pine bark; spruce bark; ultra-short-chain PFAS; short-and long-chain PFAS; elemental analysis; field-test;

    Abstract : PFAS are anthropogenic substances used in many different industrial operations and products because of their unique properties. Due to their negative impact on human health and environmental bioaccumulative characteristics different authorities have addressed the issue. In Sweden the limit is4 ng/L for four different PFAS in drinking water. READ MORE

  3. 2. Ammonium and nitrate sorption by biochar

    University essay from SLU/Dept. of Soil and Environment

    Author : Yasser Alrhban; [2023]
    Keywords : biochar nitrogen; retention; dialysis; absorption; adsorption; ammonium; nitrate;

    Abstract : Biochar has recently drawn attention due to its ability to increase soil fertility, sequester carbon and its expected effect on reducing the leaching of elements from the soil, especially nitrogen. The possibility of using biochar as a soil amendment to reduce the amount of nitrogen leaching, and then reducing the quantities of nitrogen fertilizers used in agriculture to avoid the bad environmental effects has become a matter of great interest.

  4. 3. 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

  5. 4. Sorption of novel side-chain fluorinated polymers to sediment - the impact of pH

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Hanna Erléus; [2022]
    Keywords : Scotchgard™; sorption; sediment; pH; side-chain fluorinated polymer surfactants; Lake Hjälmaren.;

    Abstract : Fluorinated compounds are produced on a large scale and their releases are contaminating the environment. Among these are side-chain fluorinated polymers found in technical mixtures of Scotchgard™, which are used as surfactants in fabric coating. READ MORE

  6. 5. Designing Mesoporous Test Sticks for Measuring PFAS Concentrations in Water

    University essay from Linköpings universitet/Nanostrukturerade material

    Author : Amanda Hillås; [2022]
    Keywords : Mesoporous material; PFAS; PFOA; PFOS; Rose Bengal; adsorption;

    Abstract : Water contamination through substances called per- and polyfluoroalkyl substances (PFAS) is a worldwide problem. Being able to measure the concentrations of PFAS in water is a first step towards beating this contamination. One alternative is to use a field test kit instead of extensive lab equipment to monitor the contaminated areas. READ MORE
