REMOVAL OF IRON FROM AQUEOUS SOLUTION BY RICE HUSK: ISOTHERM AND KINETIC STUDY

<p>This work was focused on iron adsorption by rice husk. The use of rice husk for the removal of iron from aqueous solution at different contact time, pH, adsorbent doses and initial iron concentration was investigated. This study was also aimed to recognize the mechanisms that govern iron re...
