چکیده

The paper presents our new results about efficiency of wastes based on hydrolyzed polyacrylonitrile textile fibers (HPAN) as sorbents in removal of some dyes from textile effluents. The effect of some experimental variables such as initial dye concentration, sorbent mass, pH, temperature, and contact time were investigated. The sorbent dye sorption systems are described using Freundlich, Langmuir and Dubinin-Radushkevich isotherm models. The laboratory experimental results performed using the textile fibres wastes indicate the good removal of dyes from aqueous medium, suggesting that these textile solid wastes correspond to the actual tendency of using non-conventional sorbtive materials to reduce the overall cost of sorbent preparation.

Utilization of Fly Ash as Low Cost Adsorbent for Treatment of Textile Dying Industry Effluents: Kinetics and Isotherms

Abstract--Textile dying industry effluents are highly toxic in nature and it contains a large number of complex metal dyes. Many dyes used in textile industries are stable to light and resistant to aerobic digestion. Thus removal of coloured waste from industrial dye effluent is a most perplexing problem to such industries and the environment. On the other hand fly ash is a major pollutant gene...

Color Removal from Simulated Textile Effluents Using Clean Electrocoagulation Technique

The present work was directed toward the successful ability of electerocoagulation to remove color from synthetic and simulated textile effluent by aluminum/iron electrodes. Two representative reactive dyes were selected for the synthetic dye system, a black dye alone and mixed dye (black, blue, red, 1:1:1 vol/vol). Several important operating parameters such as electrode material, initial pH(3...
