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...
متن کاملRemoval of fluoride from drinking water by adsorption onto Activated Alumina and activated carbon
The ability of activated alumina and activated carbon to remove Fluoride from aqueous solution has been investigated. The studies were carried out as functions of contact time, concentration and pH. The data indicate that activated alumina surface sites are heterogeneous in nature and that fits into a heterogeneous site binding model. The optimum pH for complete removal of Fluoride from aqueous...
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...

متن کاملRemoval of Chromium from Chromium(VI) Solutions by Adsorption and Reduction Using Immobilized Persimmon Gel
The removal of chromium(VI) from an aqueous solution using persimmon gel was examined. The amount of chromium(VI) removed was strongly affected by the pH of the solution, with all chromium(VI) being removed at pH 2 or lower. However, in a solution containing, 15 mg dry weight of immobilized persimmon gel, the amount of removed chromium(VI) decreased as the pH increased. A part of chromium(VI) w...
