Modeling of Fixed Bed Adsorption Column Parameters of Iron(II) Removal Using Ferrihydrite Coated Brick

Fixed-bed operating experimental column conditions were studied to evaluate the performance of brick from Bangui Region (in Central African Republic), coated with iron oxyhydroxide (ferrihydrite) for removal iron(II) aqueous solution. The prediction theoretical breakthrough profiles using Bohart and Adams sorption model was employed achieve characteristic parameters such as depth exchange zone, time required zone move vertically, moving rate adsorption capacity useful fixed-bed reactor investigated under varying conditions. effects bed flow on studied. Our finding revealed that Brick ferrihydrite a very efficient media Fe(II) ions water. data showed (10.3 ± 0.6 cm) (0.208 0.006 cm/min) respectively (adsorption zone) independent variability height adsorbent column, however variations affect zone. service (BDST) used permitted us predict times columns operated at various rates depths these predicted values compared values.
