Abstract

As a low cost adsorbent source, a mixture of activated animal bones has been investigated on their efficiency in chromium ion removal from aqueous solution. Adsorption parameters such as contact time, biosorbent size, pH, biosorbent dosage, temperature and concentrations were investigated. Maximum adsorption of hexavalent chromium occurred at 35minutes, 53µm size of adsorbent, pH = 6, 70mg/L of chromium ion, 3g of adsorbent dosage and 303K. The experimental data from the adsorption processes were all tested with Langmuir and Freundlich isotherms. Both isotherms showed good correlations. The higher value of R² = 0.9938 from Freundlich isotherm over the R² = 0.99 value of Langmuir isotherm showed a better fitness of the adsorption process to Freundlich isotherm over Langmuir model. It can be concluded that any activated carbon from the bones of Cow, Donkey, Chicken and Horse are effective and can be used in industries for removal of hexavalent chromium.
