Background & Aims of the Study: Due to widespread use and adverse effect of dyes, the removal of dyes from effluents is necessary. This study was aimed to remove the reactive blue 19 dye removal from aqueous solution by dried Lemna minor. Materials and Methods:  The effect of various parameters including contact time, solution pH, adsorbent dosage and dye concentrati...

Erythrosine B is widely used for dyeing in various applications, especially in the food industry, despite its already proved toxicity and carcinogenicity. Therefore, the purpose of this study is to evaluate the efficiency of the synthesis process of US/S2O8-2 in removing erythrosine B dye from aqueous solution. In this experimental study, the removal of erythros...

an agricultural waste and eco-friendly biosorbent i.e. rice husk has been used as a cheap adsorbentfor the removal of methylene blue dye from aqueous solutions. the physical properties of the developedadsorbent were characterized using ftir. the study was realized using batch experiments. the effectsof contact time, ph, initial dye concentration, biosorbent dose and temperature were investigate...

Approximately 10-20% of the total dyes in the world is consumed in the textile industry. The present study aimed to investigate the photocatalytic activity of zinc oxide nanoparticles (ZnO) immobilized on synthetic activated carbon in the removal of the acid blue 113 dye from aqueous solutions. This experimental study was conducted in a photo-reactor with the useful volume of one liter. The eff...

Background and Objective: Chemical dyes used in the textile wastewater besides having harmful effect on the environment, have carcinogenic and mutagenic effects. Methylene blue has harmful effect on living organisms in short period of exposure. The goal of this study was optimization of the catalytic ozonation process by pumice modified by magnesium nitrate in removal of methylene blue dye ba...

Fleece rot was induced in 15 young Merino ewes by treatment with repeated application of simulated rain. Forty days after induction, treated and five control ewes were subjected to 50 mm of simulated rain which contained a water soluble dye. Treated ewes absorbed significantly more water than controls (2.3 kg to 1.5 kg). Wool samples were collected at ten cm intervals along the dorsal midline t...

The activated charcoal was used for the removal of alizarin red dye from aqueous solution. Different parameters such as effect of contact time, initial dye concentration and pH were investigated. It was observed from the concentration study that the amount of dye adsorbed per unit mass of the adsorbent increased with increase in dye concentration. The pH study presented that the adsorption of d...

Textile wastewater contains a number of dyes which are known to be toxic and carcinogenic. In this study the results show that the Fenton (Fe2+/H2O2) process is an efficient method for the removal of Acid Brown 14 (A.BR14) and Cationic Blue 41 (C.B41) dyes from textile wastewater. In this method, two reagents Fe2+and H2O2 are used and do not require any additional energy. Several experiment...

Introduction: Dyes are one of the most important existing pollutants in textile industrial wastewater. These compounds are often toxic, carcinogenic, teratogenic, and non- biodegradable. Carcinogenic and mutagenic potential of some azo dyes as a category of common dyes in different types of industries has been reported. Reactive red 198 is one of the azo dyes that are currently used in the text...

The mechanism of Methylene Blue adsorption on acid activated carbon Vitex Negundo Stem (AAVNS) has been studied through batch experiments. Generally, dyes are organic compounds used as coloring products in chemical, textile, paper, printing, leather, plastics and various food industries. The need for the treatment of dye contaminated waste water passed out from the industry. In this study, Vite...
