  1. 1. Analysis of fatty acids in fatty acid-based herbicides by gas chromatography

    University essay from Lunds universitet/Kemiska institutionen

    Author : Mohamad Abd Elwadood; [2023]
    Keywords : Analytical Chemistry; Fatty Acids; Gas Chromatography; Green Herbicides; Retention Index; Flame Ionization Detector; Mass Spectrometry; Supercritical Carbon Dioxide Extraction.; Chemistry;

    Abstract : Fatty acids-based herbicides are considered to be a green alternative to synthesized weed control products. However, the environmentally sustainable effect of those herbicides needs more investigation to be confirmed. READ MORE

  3. 2. Influence of supercritical carbon dioxide (scco2) dyeing parameters on color fastness of polyester fabric dyed with disperse dye : A study towards minimizing the energy consumption of polyester (pet) fabric dyeing with azo disperse dye

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Tapas Das; [2023]
    Keywords : Supercritical fluid dyeing; polyester PET fabric; coranger orange PE3330; color fastness; ideal dyeing conditions; eco-friendly;

    Abstract : Amid growing environmental concern and continuous depletion of natural resources (such as water), the textile industry is constantly searching for sustainable production process. Traditional dyeing processes, notorious for their enormous water consumption, have led society to search alternative dyeing method. READ MORE

  4. 3. Dissolution kinetic study of limonene in supercritical carbon dioxide by in-situ Raman spectroscopy

    University essay from Lunds universitet/Kemiska institutionen

    Author : Cristiana Buzolin; [2016]
    Keywords : limonene; Raman spectroscopy; supercritical carbon dioxide; dissolution kinetics; solubility; analytical chemistry; analytisk kemi; Chemistry;

    Abstract : Understanding the dissolution kinetics is important in the experimental determination of solubility, the efficiency of extractions, the rate of reactions and in general any heterogeneous process. Despite the extensive use of supercritical fluids, studies regarding the dissolution kinetics of compounds in supercritical carbon dioxide (scCO2) using analytical methods are limited in the literature.

  5. 4. Identification of Swelling cause on Rubber Gaskets

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Jenny Fagerland; [2011]
    Keywords : EPDM gummipackningar; svällning; Analysmetod; lättflyktiga ämnen; svårflyktiga ämnen;

    Abstract : The aim of this master thesis was to develop an analysis method which identifies the swelling cause of EPDM rubber gaskets. The method shall facilitate failure investigation of rubber gaskets used in plate heat exchangers which require both determinations of volatile and involatile compounds as well as polar and non-polar compounds.
