Abstract

The breakthrough curves of the particles of magmatic rock to uptake Fe3+ ions from aqueous solution were investigated using a fixed-bed sorption column. The effect of inlet Fe3+ concentration, feed flow rate, bed height, initial solution pH and particle size on the breakthrough characteristics of the sorption system were investigated. The highest experimental bed capacities for Fe3+ ions was obtained to be 3.65 mg.g-1 at inlet Fe3+ concentration of 75 ppm, bed height of 5 cm and flow rate of 5 mL.min-1, pH of 5 and particle size of 0.25-0.5 mm, respectively. The results indicated that magmatic rock material is a suitable sorbent for the uptake of Fe3+ ions from an aqueous solution.
