can accelerate the chemical reduction of azo dye by shuttling electrons from primary electron donors such as sulfide to azo dyes. Three different types of R.M. were studied on the enhancement of chemical reduction of Acid Orange 7. The electron shuttle ability of these types of R.M. with ...
A range of light-transmission wavelengths given to the polarization filters 33 and 35 can be changed depending on dye compounded into the polarization filters 33 and 35. For example, if the wavelengths for red are desired to pass, azo-type dyes are removed. The LC containing layer 37, which...
All the type of dyes are in demand in the market due to the growing industries in developing countries. Future market trends are favorable for India being a developing country. The recent trade skirmishes between US and China has given India a chance to grow its domestic market by serving th...
Precious stones belong to the rare high-grade decorative materials, and the production of buttons is very few. Gemstones currently used for button production are mainly low-grade jewels and artificial crystals. Artificial crystal buttons are bright and transparent, and consumers are easy to accept. ...
Three azo dyes, Reactive Orange 96, Reactive Violet 5 and Reactive Black 5, and two phthalocyanine dyes, Reactive Blue 15 and Reactive Blue 38, were chosen as representatives of commercially used reactive dyes. From the 18 tested fungal strains only Bjerkandera adusta , Trametes versicolor and ...
However, the degradation of organic dyes over time due to photobleaching impacts their longevity and efficiency. They also require high-power pump sources, leading to higher operational costs.3,4 Semiconductor Lasers Semiconductor lasers, commonly known as laser diodes, use a semiconductor junction as...
Increasing amount of dyes in the ecosystem particularly in wastewater has propelled the search for more efficient low-cost adsorbents. The effective use of
An analytical procedure based on microwave-assisted extraction (MAE) and standard addition was applied for the determination of banned azo dyes in bovine, sheep, and goat leather. Standard addition at four different concentration levels was performed using azo dyes, dissolved either in methanol or wa...
Nitrogen- and Fe(III-) doped TiO2 nanoparticles were better in degrading azo dyes and phenol, respectively, than commercially available TiO2 nanoparticles [367, 368]. TiO2 nanoparticles deposited onto porous Al2O3 were used effectively for the removal of TOC in a study [369]. TiO2 ...
(Morocco) and international scales. Recent studies about the adsorption treatment process for the removal of dyes from the aqueous solution with different adsorbents recognized as a sustainable solution in terms of minimization, recovery, and reuse were evaluated. It is also aimed to synthesize the ...
