Removal of hexavalent chromium using coffee husk
The potential to remove chromium(VI) from aqueous solutions through biosorption using coffee husk was investigated. The effects of pH, contact time, initial concentration and adsorbent dosage on the adsorption of Cr(VI) were studied. The data obeyed Langmuir and Freundlich adsorption isotherms. The Langmuir adsorption capacity was found to be 44.95 mg/g. The Freundlich constants Kf and n were 1...

Background and Aim: Hexavalent chromium is a heavy metal with harmful effects on surface and ground water. Its removal from contaminated water and waste water has received great interest in recent years. This study aimed to evaluate the absorption of hexavalent chromium from aquatic environments using functionalized carbon produced from rice husk as an inexpensive and biological adsorbent. Mat...

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...
