Cr(III) REMOVAL FROM AQUEOUS SOLUTIONS BY ADSORPTION
The adsorption of Cr (III) on the adsorbent produced from lignite coal was studied as a function of time, amount of adsorbent, pH and temperature. Cr (III) adsorption data obeyed Freundlich, Langmuir and Lagergren equations. The values of ?H0, ?S0 and ?G0 were calculated. The results showed that ads...

| description | The adsorption of Cr (III) on the adsorbent produced from lignite coal was studied as a function of time, amount of adsorbent, pH and temperature. Cr (III) adsorption data obeyed Freundlich, Langmuir and Lagergren equations. The values of ?H0, ?S0 and ?G0 were calculated. The results showed that adsorption is endothermic. The negative free energy values indicate that the process of Cr (III) adsorption is spontaneous and favoured at high temperatures. The adsorption of Cr (III) in the presence of different cations was also studied at 200 C. The results were correlated with the ionic potential of cations. |
