Adsorption kinetics of malachite green onto activated carbon prepared from Tunçbilek lignite

Adsorption for Dyes on Activation Carbons from Japanese Cedar Wood Prepared by Precarbonization and Two-stage Composite Activations with Wood Ash and Steam

“…Therefore, when the dye liquid pH > 5, the quantities of BY2 and BG4 dyes adsorbed by P200-0.25-750 become balanced, and there is no obvious change, which is identical to the result of Hameed and El-Khaiary (2008) [49], meaning that there is no significant change in adsorbance when the pH > 5 solution in the adsorption of malachite green dye on bamboo ACs. In addition, the adsorption of BY2 and BG4 dye liquids with different pH values on P200-0.25-750 is similar to the previous findings of adsorption of BY2 or BG4 dye liquid with different pH values on ACs [49], [74], [78].…”

Adsorption of Malachite Green from Aqueous Solutions by PNSBP: Equilibrium, Kinetic and Thermodynamic Studies

“…Textile industry rank first among other industries worldwide today in usage of dyes for coloration of fiber, which generate huge volume of waste water every year [5-.6]. Dyes being an important recalcitrant persist for long distance in flowing waters and retards photosynthetic activity of aquatic biota by blocking out the sun light and utilizing dissolved oxygen and also decreases the recreation value of stream [7]. Most of the dyes are carcinogenic and toxic in nature and when discharged into the water they pose serious hazard to the aquatic biota [8].…”

Adsorption of Crystal Violet on Activated Carbon Prepared from Coal Flotation Concentrate

“…Activated carbon is the most popular adsorbent, but production and regeneration is expensive, so considerable attention has been given to find low cost and easily available carbon sources, like local low-rank coal [3,4]. In the present study, Zilan-Van coal, having high ash and moisture content, was selected as a carbon source to produce activated carbon.…”
