In this study, Remazol Yellow (RR) removal was investigated by Saccharomyces cerevisiae immobilized on pumice stone. For the immobilization process, a new technic was used and immobilization matrix HCl pretreated pumice stone was added to the growth medium of microorganism. pH, initial biosorbent (Co), and dye concentration (Cb) effect on biosorption were optimized thr...

Disperse dye inks are used in the inkjet textile printing of polyester fabrics. We aimed at developing a black disperse dye ink consisting of yellow, magenta, and cyan dyes that met the exacting requirements of safety, image durability, and storage stability. One difficulty we met was dye particles tending to aggregate/agglomerate, leading to sedimentation and the threat of head clogging and/or...

Abstract Recently, the adsorption process relied on use of low-cost, available and eco-friendly materials to reduce costs. Pomegranate peels(PPs) have been used as environmental inexpensive bio-sorbent material remove dye (brilliant yellow) from aqueous solution. characterization via two techniques like FTIR, FESEM analyze morphology chemical groups before after sorption brilliant yellow dye, A...

Though an important and chronic source of dyes released to the environment, determination release that occurs during household or industrial washing is usually disregarded. The main scope this study reveal extent dye through washing, understand if modification cotton fabrics with cationic polymers could reduce it. Modified fabrics, dyed Acid Blue 281 (AB) by a mixture reactive Novacron Yellow S...

Seeds of east Australian Grevillea species germinate in response to fire-related cues such as heat and smoke. The seed coat is responsible for dormancy in G. linearifolia: a possible dormancy mechanism is the existence of barriers to diffusion of large molecular weight compounds in the seed coat. Such internal barriers are known to be involved in the dormancy of fire-responsive seeds overseas e...

The purpose of this research is to establish the experimental conditions for removal of Cibacron Brilliant Yellow 3G-P dye (CBY) from aqueous solutions by sorption onto coffee husks as a low-cost sorbent. The effects of various experimental parameters (e.g. initial CBY dye concentration, sorbent mass, pH, temperature) were examined and the optimal experimental conditions were determined. The re...

The study was designed for isolation and characterization of azo dye decolourizing bacteria which is a prerequisite for developing a microorganism-facilitated treatment of polluting dyes. In this study nine types of bacteria which were able to decolourize three types of azo dyes (Blue H/C, Red 3B and Yellow 3R dye) were isolated from textile effluents collected from Gazipur industrial area in B...
