Abstract Studies on the effectiveness of removing colored impurities from wastewater after dyeing process obtained five plants located in Lodz region Poland were performed as well a comparative spectrophotometric analysis before and treatment, visible range absorption 350–750 nm, attributed to dyes different groups with structures chromophoric systems. It was found that method calculating diffe...

The goal of this study was to utilize carrier for accelerating the rate of dyeing not only to enhance dyeing of polyester fabrics dyed with disperse dyes 3a,b, but also to save energy. Both the color strength expressed as dye uptake and the fastness properties of the dyed fabrics were evaluated.

In this work, the performance of medium-pressure UV/peracetic acid (MPUV/PAA/H2O2) was explored on removing reactive black 5 (RB5), aniline (ANL), and polyvinyl alcohol (PVA), three typical refractory contaminants in printing dyeing wastewater, compared with MPUV/H2O2. MPUV/PAA/H2O2 showed 75.0, 44.9, 57.7% removals RB5, ANL, PVA, respectively, within min. The removal RB5 increased from 68.98 t...

Abstract: The colored organic or inorganic chemical compounds which can impart colour to other substance are the Dyes did significant applications in most industrial sectors like textile industry, leather paper plastic, foodstuff industry etc, color their products. Due large volume of dye use these businesses, a quantity wastewater containing organics is generated. Because insufficient dye-fibe...

This paper took the objective of preparing high-performance, low-cost biological adsorbent for printing and dyeing wastewater, adsorption experiment dyestuff wastewater with high chromaticity biodegradability was studied. The Methylene Blue adsorbed by prepared Humulus Japonicus Leaves (HJ), effects time, pH, dosage adsorbent, initial concentration temperature on process were investigated, mech...
