  1. 1. Solubility of arsenic in untreated and ZVI-treated contaminated aquifer material

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Oscar R. Davies; [2022]
    Nyckelord :Hjältevad; zerovalent iron; phosphate extraction; Oxalate extraction; Visual MINTEQ; geochemical modelling;

    Sammanfattning : Arsenic (As) is a toxic element to all life and exists in nature both naturally and anthropogenically. Naturally As contaminated soils are formed due to high geogenic background As concentrations which is released when bedrock is eroded. Asia is a continent with a high amount of naturally As contaminated soils and groundwater. LÄS MER

  3. 2. Separation of Cobalt and Nickel using CYANEX 272 for Solvent Extraction

    Master-uppsats, KTH/Kemiteknik

    Författare :Caroline Kihlbom; [2021]
    Nyckelord :Solvent extraction; cobalt-nickel separation; CYANEX 272; pregnant leach solution; cobalt sulphate; Vätskevätskeextraktion; kobolt-nickel separation; CYANEX 272; laklösning; koboltsulfa;

    Sammanfattning : This project aimed to examine the separation of cobalt and nickel using solvent extraction (SX) with the extractant CYANEX 272 (C272). It was intended to investigate the Co-Ni separation in a sulphate-based leach solution in presence of other contaminants. LÄS MER

  4. 3. Remediation of an arsenic-contaminated anoxic aquifer in hjältevad with zerovalent iron : assessment and modelling of sorption strength and solubility of arsenic

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Kathrin Leicht; [2021]
    Nyckelord :arsenic remediation; zerovalent iron; anoxic aquifer;

    Sammanfattning : In-situ injection of zerovalent Iron (ZVI) particles to remediate contaminated groundwater is a widely applied approach. However, studies assessing the remediation and immobilisation mechanisms of Arsenic (As) under anoxic field conditions with zerovalent iron particles are lacking, especially for nanosized sulphidated ZVI (S-nZVI) and oxidic shell free ZVI (OSF-nZVI).

  5. 4. Automated analysis of battery articles

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Strukturkemi

    Författare :Robin Haglund; [2020]
    Nyckelord :battery chemistry; chemical engineering; chemistry; engineering; battery; li-ion; lithium-ion batteries; LFP; lithium iron phosphate; machine learning; regular expressions; classification; SVM; keras; scikit-learn;

    Sammanfattning : Journal articles are the formal medium for the communication of results among scientists, and often contain valuable data. However, manually collecting article data from a large field like lithium-ion battery chemistry is tedious and time consuming, which is an obstacle when searching for statistical trends and correlations to inform research decisions.

  7. 5. Protein environment and structure in neat and hydrated deep eutectic solvents

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Jenny Xiang; Medina Basic; [2020]
    Nyckelord :Deep eutectic solvents; proteins; BSA; lysozyme; choline chloride:glycerol; choline chloride:urea; choline acetate:glycerol; UV-Vis; fluorescence; FT-IR; hydrated deep eutectic solvents; pharmaceutical technology; läkemedelsteknologi; Technology and Engineering;

    Sammanfattning : The use of deep eutectic solvents (DESs) has a great potential in the pharmaceutical field due to its many advantages such as biocompatibility, low toxicity and biodegradability. Studies have also shown that proteins can be successfully incorporated into DESs. LÄS MER
