EXAMPLE:A compound shown by formula II. USE:Dye for dying various kinds of fiber materials, leathers, paper and pulp in yellow, reddish yellow, greenish yellow, etc., at an excellent dyeing rate and dyeing ratio with light resistance and fastness to wetting. PREPARATION:An amine shown by ...
Dye contamination in the natural environment presents various multifaceted risks [1]. For example, organic dyes can reduce light penetration, interfering with the photosynthetic processes of aquatic organisms, leading to an imbalance in aquatic ecosystems. Organic dyes have been reported to have ...
Synthesis of ZnS/CQDs nanocomposite and its application as a photocatalyst for the degradation of an anionic dye, ARS. Synthesis of ZnS/CQDs nanocomposite and its application as a photocatalyst for the degradation of an anionic dye. Superlattice Microstruct. 2016, 98, 86-... Kaur,Sharanjit,Sharm...
A process is described for converting sparingly soluble salts of anionic dyes and fluorescent brighteners into more soluble salts by means of cation exchange without intermediate isolation of the free dye acid, which comprises carrying out the cation exchange by using Donnan dialysis. The concentrated...
Composition for dyeing fibers with a subject-matter of the cationic direct dye and an anionic surfactant - the active agent. Composition for dyeing keratinic fibres, especially human hair includes: a cationic, cyclic azo or ethylene, and nitrogen heterocyclic or benzene derivativ... G Lang,C Jea...
The use of liquid electrolytes in dye-sensitized solar cells (DSSCs) is a significant obstacle for the commercialization of DSSCs. Even the idea of evaporation or leakage of electrolyte profoundly shakes the trust in DSSCs, which are expected to last for a long time when used outdoors. At ...
Polyethylene terephthalate and terephthalate copolyesters in fabrics are treated with phosphoric acid followed by an alkyl polyamine such as ethylene diamine to render the fabrics more dyeable with ac
For example crystal violet (CV) dye, belongs to cationic dyes, which is frequently employed in textile factories to color cotton and silk, as well as in the manufacture of paints and inks. CV dye is employed to recognize bloody fingerprints [7]. CV may cause mild irritation of the eyes ...
In this work, we report a facile synthesis of bimetallic solid comprised of Ag and Cu nanoparticles (Ag-Cu NPs) and its enhanced catalytic performance towards the degradation of cationic and anionic dye. Three Ag-Cu NPs samples with different Cu/Ag ratios (1:3, 2:2, and 3:1) were synt...
The as-prepared chitosan sponges were tested as the adsorbents for the anionic dye due to the cationic nature of chitosan and porous structure. Rose bengal (RB) dye is used as an example of anionic dyes to investigate the adsorption performance, mechanisms, and kinetics of chitosan sponges. A...
