  1. 1. Investigation of Adsorption and Retention of Charged Compounds In RPLC

    University essay from Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Author : Emma Fryxelius; [2022]
    Keywords : adsorption; adsorption isotherm; charged compounds; promethazine hydrochloride; propranolol hydrochloride; mixed-mode; retention; RPLC;

    Abstract : The adsorption isotherm of two weak bases, Promethazine hydrochloride and Propranolol hydrochloride, were determined with isocratic reversed-phase liquid chromatography, with a 60 w% methanol in 20 mM sodium acetate buffer pH 4 as the mobile phase, and calculated by the elution by characteristic points method. The data obtained from the method were then fitted into the Langmuir isotherm and the electrostatically modified Langmuir. READ MORE

  2. 2. Moisture Transport in PA6

    University essay from Lunds universitet/Hållfasthetslära; Lunds universitet/Institutionen för byggvetenskaper

    Author : Emanuel Markström; [2022]
    Keywords : Technology and Engineering;

    Abstract : Polyamide 6 (PA6) is known to absorb water from its environment due to its chemical structure. The water absorption leads to changes in the mechanical properties as well as an increase in volume (swelling) of the polyamide. READ MORE

  3. 3. A study of the adsorption isotherms of Ion-pair reagents

    University essay from Karlstads universitet

    Author : Mehmet Bilici; [2022]
    Keywords : Tributylamine; adsorption isotherm; liquid-liquid extraction; gas chromatography;

    Abstract : In this project, the optimization of obtaining adsorption isotherms for the ion pair reagent, tributylamine was tested. The goal was to have a better understanding of the chromatographic process when separating biomolecules, such as oligonucleotides. READ MORE

  4. 4. Temperature-dependent waterbinding on potassiumbirnessite : A potential sorbent for atmospheric water harvesting

    University essay from Umeå universitet/Kemiska institutionen

    Author : Hanna Oderstad; [2022]
    Keywords : ;

    Abstract : The nanolayered manganese oxide birnessite (MnO2) is a naturally occurring mineralin soils and sediments. Its ability to capture and store water within its interlayers, andits great solar absorptivity, could be a part of the solution to global water shortage. READ MORE

  5. 5. 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
