1. 1. Modelling Competitive Sorption of Per- and Polyfluoroalkyl Substances (PFASs) to Soil and Sorbents

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

   Author : Linnea Georgii; [2021]
   Keywords : PFAS; modelling; competitive sorption; adsorption; isotherms; PFAS; modellering; konkurrenseffekter; adsorption; isotermer;

   Abstract : Per- and polyfluoroalkyl substances (PFASs) have become contaminants of increasing concern to society due to the contamination of drinking water and the ecosystem. A better understanding of the sorption and transport of PFASs in soil systems is urgently needed, however there have been few studies dedicated to investigating competitive sorption among PFASs, and there is no available model to model such effects.

3. 2. Filter Materials for Sorption of Cu and Zn in Stormwater Treatment: A Batch Equilibrium and Kinetic study

   University essay from Luleå tekniska universitet/Arkitektur och vatten

   Author : Per-Albin Norman; [2018]
   Keywords : Stormwater; Treatment; Metals; Sorbents; Batch equilibrium test; Isotherms; Kinetic test; Catch basin inserts;

   Abstract : Urban stormwater is today recognized as a significant source of pollution that has contributed to the deterioration of water quality in lakes and streams. Of the pollutants, metals are commonly occurring in stormwater and can cause major damage when released into the receiving waters. READ MORE

4. 3. Remediation of Contaminated Groundwater Using a SpinChem® Rotating Bed Reactor : Competitive Sorption of Metal(loid)s in Complex Solutions under Varying Geochemical Conditions

   University essay from Luleå tekniska universitet/Geovetenskap och miljöteknik

   Author : Pär Alapää; [2018]
   Keywords : Groundwater Remediation; Competitive Sorption; SpinChem;

   Abstract : The potential of utilizing a new form of chemical processing technology called SpinChem® Rotating Bed Reactor (RBR), in combination with different reactive materials, for the purpose of remediating multi-contaminated aquifers under changing environmental conditions, was investigated using laboratory studies and geochemical models. Four different reactive materials, or combinations thereof, were tested: heat-treated peat powder combined with zero-valent iron (ZVI); IronPeat, which consists of peat powder coated with a ferriferous hydrosol (FFH); and a powdered steel waste product.

5. 4. Arsenic (V) and Phosphate sorption to Swedish clay soils - Freundlich sorption modelling.

   University essay from KTH/Miljögeokemi och ekoteknik

   Author : Luhuvilo Mwamila; [2011]
   Keywords : Freundlich modeling; Arsenic V ; Phosphate; Adsorption; Swedish clay soil;

   Abstract : This thesis is an attempt to analyze and interpret the behavior of the two elements arsenic and phosphorus when released into the environment. Both of them may occur naturally in the environment but also may be added to the environment for certain purposes e.g. as pesticides and fertilizers respectively or through anthropogenic sources.
