AbstractWe prepared Fe(3)O(4) particles and two types of composite magnetic particles derived from Fe(3)O(4) and bis(trimethoxysilylpropyl)amine (TSPA), and from Fe(3)O(4) and a flocculating agent 1010f (a copolymer of acrylamide, sodium acrylate, and [2-(acryloyloxy)ethyl]trimethylammonium chloride). Using these particles, boron adsorption in aqueous solution was comprehensively investigated. The adsorption was found to occur rapidly in the first 2 h and the particle composition did not have a significant effect on the equilibrium time. We found that Fe(3)O(4)-TSPA particles presented the highest adsorption capacity, whereas the pure Fe(3)O(4) particles showed the lowest capacity. For all particles, amount of boron adsorption decreased with the initial pH in the order of 6.0 > 2.2 > 11.7. In general, the adsorption amount appeared to decrease with the increase in ionic strength. We propose that boron is adsorbed in the form of both H(3)BO(3) and B(OH)(4)(-) through the interactions of hydrogen bonding, electrostatic and hydrophobic attractions. The information gained in this study would be helpful for both understanding the adsorption mechanism and designing low-cost and easily available adsorbents for boron. (C) 2009 Elsevier B.V.
