BACKGROUNDA column sorption study was carried out using calcium alginate gel beads as adsorbent for the removal of boron from aqueous solutions. The breakthrough curve was obtained as a function of pH, initial concentration of boron, feed flow rate, adsorbent mass and column diameter. The breakthrough capacity values and adsorption percentage of calcium alginate gel for boron were calculated. Column data obtained at different conditions were described using the Adams-Bohart model and bed-depth service time (BDST), derived from the Adams-Bohart equation to predict breakthrough curves and to determine the characteristic column parameters required for process design.; RESULTSThe maximum adsorption percentage of boron on calcium alginate gel beads using an initial concentration of boron of 50 mg L-1 at pH 11 and room temperature (201 degrees C) was calculated to be 55.14%.; CONCLUSION<p id=
