  2. 1. Determination of Banned Azo Dyes in Leather

    Author : Lars-Henric Ahlström; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytisk kemi; Analytical chemistry; extraction; azo dyes; aromatic amines;

    Abstract : Dyes are commercially indispensable and the expanding industry offers a complete palette of colors. Azo dyes constitute the largest chemical class of synthetic dyes because of their versatility, low price, and ease of production. READ MORE

  4. 2. Contact allergy to textile dyes. Clinical and experimental studies on disperse azo dyes

    Author : Laura Malinauskiene; Yrkes- och miljödermatologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Disperse Orange 1; Disperse Yellow 3; metabolites; azo reduction; p-aminodiphenylamine; 4-nitroaniline; 2-amino-p-cresol; 4-aminoacetanilide; TLC; HPLC; guinea pig maximisation test.;

    Abstract : Disperse dyes are the most common allergens among textile dyes. It is not known whether the purified dyes, impurities in the commercial dyes, or metabolites are the actual sensitisers. Moreover, it is not known whether those disperse dyes that are now present in test series are actually used in textile dyeing today. READ MORE

  5. 3. Imine/azo-linked microporous organic polymers : Design, synthesis and applications

    Author : Chao Xu; Niklas Hedin; Dave Adams; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Microporous organic polymers; CO2 capture and separation; post-modification; chemisorption; heterogeneous catalysis; Materials Chemistry; materialkemi;

    Abstract : Microporous organic polymers (MOPs) are porous materials. Owing to their high surface area, tunable pore sizes and high physicochemical stability, they are studied for applications including gas capture and separation and heterogeneous catalysis. In this thesis, a series of imine/azo-linked MOPs were synthesized. READ MORE

    Author : Bengt Nygård; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : .... READ MORE

  7. 5. Treatment of Textile Wastewater by Combining Biological Processes and Advanced Oxidation

    Author : Marisa Punzi; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Azo dye; textile wastewater; biological treatment; biofilm; microbial community; DGGE; green algae; photo-Fenton; ozone; toxicity; mutagenicity; LCA; cost analysis;

    Abstract : Treatment of textile wastewater is challenging because the water contains toxic compounds that have low biodegradability. Dyes, detergents, surfactants, biocides and more are used to improve the textile process and to make the clothes resistant to physical, chemical and biological agents. READ MORE
