Removal of Chromium (III) and Arsenic (III) by using Coal Ash as Adsorbent
The adsorption of Cr(III) and As(III) by using coal ash from thermal power plants in batch mode ,The effect of adsorbent agitation speed, dose, pH, contact time and agitation speed on the adsorption of Cr(III) and As(III) by coal ash is examined. Adsorption equilibrium was achieved in 50–55 min. The Langmuir, Temkin and Freundlich adsorption isotherms were used to observed sorption phenomena. T...
متن کاملCoal Ash as a Low Cost Adsorbent for the Removal of Xylenol Orange from Aqueous Solution
The removal ofxylenol orange from aqueous solution onto the coal ash was investigated at room temperature. The results show that the adsorption capacity of xylenol orange increased as the adsorption time increased and then equilibrium established after 30 min adsorption time. The results obtained revealed that the coal ash removed about 80 % of xylenol orange from the aqueous solution withi...
متن کاملEfficiency in phenol removal from aqueous solutions of pomegranate peel ash as a natural adsorbent
Background: Phenol is an organic pollutant found in industrial effluents that is very toxic to humans and the environment. This study used pomegranate peel ash as a natural absorbent to remove phenol from aqueous solutions. Methods: In this study, pomegranate peel ash in different doses was used as a new adsorbent for the removal of phenol. The effects of contact time, pH, adsorbent dose and i...
متن کاملRemoval of Cr(VI) from Wastewater using Fly ash as an Adsorbent
Cr(VI) is a highly toxic metal ion and considered a priority pollutant released from various chemical industries. Treatment methods to remove Cr(VI) from water and wastewater include chemical precipitation, ion exchange, membrane separation, electro-coagulation and reduction. These methods are not economically viable for large scale treatment of wastewater that is rich in Cr(VI). Adsorption is ...
متن کاملNanostructured Fe2O3/Al2O3 Adsorbent for removal of As (V) from water
The presence of arsenate in drinking water causes adverse health effects including skin lesions, diabetes, cancer, damage to the nervous system, and cardiovascular diseases. Therefore, the removal of As (V) from water is necessary. In this work, nanostructured adsorbent Fe2O3/Al2O3 was synthesized via the sol-gel method and applied to remove arsenate from polluted waters. First, the Fe2O3 load ...
