Comparative removal of emerging contaminants from aqueous solution by adsorption on an activated carbon

Removal of chromium (VI) from aqueous solution by adsorption using cousinia eryngioides boiss and activated carbon

Adsorption capacity of Cr (VI) onto cousinia eryngioides boiss, activated carbon was investigated in a batch system by considering the effects of various parameters like contact time, initial concentration, pH, temperature, agitation speed, absorbent dose and particle size. Cr (VI) removal is pH dependent and found to be maximum at pH 2.0. The amounts of Cr (VI) adsorbed increased with increase...

Phenol Removal from Aqueous Solutions by Adsorption on Activated Carbon of Miswak’s Root Treated with KMnO4

Background and Purpose: Phenol and derivatives are common pollutants of drinking water which are blamed for crucial adverse effects such as poisoning, cancer, and malformation. In this study, an activated carbon of Miswak’s root (MR) was used for the removal of phenol from aqueous solutions as a low-cost and high surface adsorbent. Materials and Methods: Adsorption exper...

Adsorption of Volatile Organic Compounds from Aqueous Solution by Granular Activated Carbon (GAC) in Batch System

Removal of Hexavalent Chromium Ions from Aqueous Solution by Adsorption Using Activated Carbon Prepared from Cucumis Melo Peel Activated carbon

Activated carbon prepared from Cucumis Melo Peel was used as adsorbent for the removal of chromium ion from aqueous solution. Adsorption experiments were performed by varying initial metal ion concentration, temperature, and pH. Freundlich and Langmuir isotherms were used to analyze the equilibrium data obtained at different adsorption conditions. Adsorption results obtained, shows that the Cr ...
