Abstract: (4266 Views)
The aim of this study is to investigate the possibility of the using rice bran as a natural and suitable adsorbent for the removal of formic acid whose is an organic acid from liquid solution and the effect of various parameters such as adsorbent dose, initial concentration adsorbate, temperature and time on the adsorption process and determination of adsorption isotherm constants. Removal of organic acids from liquid solutions is an important environmental challenge. Batch adsorption experiments showed that the adsorption increased with the increasing of the amount of adsorbent, initial concentration of adsorbate and decreasing temperature and adsorption process is reached the equilibrium state after one hour. The adsorption data was analyzed using the various isotherm models. From these various isotherm models, the adsorption process obeys the Langmuir and Freundlich adsorption isotherms. The results show a good agreement with both methods.The average amount of adsorbate per 3 degrees of freedom and confidence 95% ، 10.39±0.095 ، is obtained
