Removal of heavy metals from industrial and hazardous wastewaters using a recycled iron-bearing material
- Southern Methodist Univ., Dallas, TX (United States). Environmental Engineering Program
An iron-bearing material deriving from surface finishing operations in the manufacturing of cast-iron components demonstrates considerable potential as a low-cost adsorbent for removal of heavy metals in aqueous waste streams. The availability of the residual iron material renders recycling and use of the material in treatment applications for metal-bearing wastewaters a potentially innovative, and cost-effective venture. Furthermore, a portion of he material exists in granular sizes that may be used in fixed bed applications. The principal aims of the present work, however, are to: (1) experimentally investigate the adsorption capacity and rate of heavy metals onto the iron sorbent in batch systems, and (2) to examine the extent to which existing mathematical models for adsorption equilibria and kinetics can quantify the experimental data and thereby serve as an aid in understanding experimental phenomena and potentially as a design tool.
