Waste Tendu Leaves From Beedi Industry Utilized For Removal of Sulphur Dye From Textile Waste Water

چکیده
An activated carbon as adsorbent is derived from waste tendu leaves (Diospyros melanoxylon) from local Beedi (Cigarette) industry for removal of sulphur dye from textile waste water. Tendue leaves were chemically treated with sulphuric acid and activated carbon prepared was analyzed by pH, moisture content, ash content, bulk density and BET surface area. The adsorption studies were performed as a function of different concentration of dye solution, contact time, pH and different adsorbent doses. The kinetics of the adsorption process follows the pseudo second-order kinetic model. Equilibrium data was analyzed using Langmuir, Freundlich and Tempkin isotherm models. The suitability of the data in different model of isotherm is determined from correlation coefficient (R2) value. The results of all isotherms model shows correlation coefficient (R2) value close to 1 and hence results fit into adsorption data. The results showed that tendu leaves a solid waste disposal from Beedi industry can be used as effective biosorbent for removal of sulphur dye from textile waste water.

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...

Contaminated water is the primary source of any disease. Water may be contaminated by number of pollutants and dyes are one of them. Malachite green (MG) dye is widely used as biocide in the aquaculture industry to controls fungal attacks, protozoan infections and also used in food and textile industries for various purposes. Surface and ground water is contaminated with dyes due to discharge o...
