Adsorption of acid dye onto activated carbons prepared from agricultural waste bagasse by ZnCl2 activation.
A series of activated carbons were prepared from agricultural waste sugarcane bagasse by chemical activation with zinc chloride (ZnCl2) as an activating agent at 500 degrees C and 0.5 h soaking time. The Langmuir surface area and total pore volume were used to estimate the average pore diameter of the carbon products. The values of the surface area and pore volume increased linearly with increa...
متن کاملAdsorption of Nickel(II) Ion From Aqueous Solution onto ZnCl2 Activated Carbon Prepared From Delonix Regia Pods (Flame Tree)
Adsorption of Nickel(II) ion onto Activated Carbon prepared from Delonix regia pods activated with Zinc chloride (DRZAC) under various experimental conditions were studied. Batch mode adsorption experiments were conducted. The characteristics of the DRZAC were determined by SEM, XRD, FTIR, BET analysis and pHZPC. The maximum removal efficiency of Ni(II) ion is 85% at pH 6. Under the chosen cond...
متن کاملAdsorption of Pb(II) by activated carbon prepared from Melia azedarach fruit: Equilibrium and thermodynamics
In this work, a low-cost activated carbon as well as non-hazardous material, with high adsorption capacity, was prepared from Melia azedarach fruit (MF) by ZnCl2 activation for the removal of Pb(II) toxic metal from aqueous solutions. The microstructure of the activated carbon was observed by Scanning Electron Microscopy (SEM). Batch experiments have been performed as a function of pH, contact ...
متن کاملAdsorption of copper, lead and cadmium from aqueous solutions by activated carbon prepared from saffron leaves
Background: Industrial development has caused the release of various pollutants including heavy metals into the environment. These toxic compounds are extremely dangerous to living beings and the environment due to their non-biodegradability, severe toxicity, carcinogenicity, the ability to be accumulated in nature and the ability to contaminate groundwater and surface water. The aim of the pre...
متن کاملAdsorption of Chromium Ion (vi) by Acid Activated Carbon
The activated carbon produced from olive stones was chemically activated using sulfuric acid, (OS-S), and utilized as an adsorbent for the removal of Cr(VI) from aqueous solution in the concentration range 4-50 mg/L. Adsorption experiments were carried out in a batch process and various experimental parameters such as effect of contact time, initial chromium ion concentration, carbon dosage, an...
