Textile industries are one of the largest consumers of water and hence producers of liquid effluents. The dyeing and finishing processes generate volumes of wastewaters in the range 45450 m3 per ton of product [1], containing salts, acids, bases, additives and unfixed dyes. A suitable treatment of these complex wastewaters should lead to a strong decline on the organic load, and desirably to a ...

Far-red emitting fluorescent dyes for optical microscopy, stimulated emission depletion (STED), and ground-state depletion (GSDIM) super-resolution microscopy are presented. Fluorinated silicon-rhodamines (SiRF dyes) and phosphorylated oxazines have absorption and emission maxima at about λ≈660 and 680 nm, respectively, possess high photostability, and large fluorescence quantum yields in water...

Plasmodium falciparum gametocytes are not associated with clinical symptoms, but they are responsible for transmitting the pathogen to mosquitoes. Therefore, gametocytocidal interventions are important for malaria control and resistance containment. Currently available drugs and vaccines are not well suited for that purpose. Several dyes have potent antimicrobial activity, but their use against...

In Rajasthan state particularly, textile mills represent an important economic sector. Pali district in Rajasthan has got largest number of textile industries in the State i.e.989 units, mostly engaged in cotton and synthetic textile printing and dyeing. These industries liberate a variety of chemicals, dyes, acids and alkalis besides other toxic compounds like heavy metals, which are known for...

Background & Aims of the Study: water pollution by synthetic organic dyes is mainly regarded as environmental and ecological critical issues worldwide. In this research, magnetite iron oxide/silica gel nanocomposite (termed as Fe3O4/SG) was synthesized chemically and then used as an effective adsorbent for removal of sulfur dyes from aqueous solution. Materials and Method...

The main goal of the study is to produce eco-friendly furniture dyes by using bio-colorants and determine color stability these in outdoor conditions. In this regard, dye extracts obtained from red beet (Beta vulgaris), safflower (Carthamus tinctorius L.), purple cabbage (Brassica oleracea), as a bio-colorant source, were applied MDF test panels mixing with water-based synthetic lacquer coating...

Shewanella decolorationis is a valuable microorganism for degrading diverse synthetic textile dyes. Here, we present an annotated draft genome sequence of S. decolorationis S12, which contains 4,219 protein-coding genes and 86 structural RNAs. This information regarding the genetic basis of this bacterium can greatly advance our understanding of the physiology of this species.

Sappan wood (Caesalpinia sappan) is very well known as a natural dye for traditional food and beverage in many countries. Recently, there are reports of sappan adulteration by adding synthetic or dyes to obtain quality color better appearance. In this study, UV-Vis absorption spectra coupled with chemometrics were used develop rapid detection raw material (authentication) from three dyes, i.e.,...
