Adsorption of the Cationic Dye Ethyl Violet on Acid and Alkali-Treated Wild Carob Powder, A Low-Cost Adsorbent Derived from Forest Waste
The effect of acid-alkaline treatment of lignocellulosic material (wild carob forest wastes) on Ethyl violet adsorption was investigated. It was found that surface chemistry plays an important role in Ethyl Violet (EV) adsorption. HCl treatment produces more active acidic surface groups such as carboxylic and lactone, resulting in an increase in the adsorption of EV dye. The adsorp...

متن کاملWaste Tendu Leaves From Beedi Industry Utilized For Removal of Sulphur Dye From Textile Waste Water
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...
متن کاملMalachite green dye, removal from waste water by adsorption
The organic dyes directly pollute the soil, water, plants and all living systems in the environment. In the present investigation, adsorption of brilliant green dye on silica from aqueous solution was studied. The dye adsorption mechanism was studied on the basic surface of silica. The adsorption parameters were optimized to maximum adsorption. The adsorption mechanism of brilliant green on sil...
متن کاملDye Waste Treatment
Dye wastes represent one of the most problematic groups of pollutants because they can be easily identified by the human eye and are not easily biodegradable. This literature review paper highlights and provides an overview of dye waste treatments performed over the three years period from 2008–2010. Noteworthy processes for the treatment of dye waste include biological treatment, catalytic oxi...
