The presence of low concentrations of arsenic in water is of serious environmental concern. Though it is a naturally occurring carcinogenic element, it could also be released into the atmosphere through numerous industrial activities. The objective of this paper is to reveal arsenic-adsorptive properties of human hair from contaminated drinking water. Human hair has been found to be extremely effective in separating oil and water from stable oil-water emulsions (recently conducted US DoE study). Both static and dynamic tests, along with numerical modeling, have been performed to observe the performance of human hair as an adsorbent. Static tests show satisfactory performance through high adsorption capacity at low concentrations. Dynamic tests demonstrate the feasibility of the technique in a packed bed column. Numerical modeling was used to conduct various parametric studies and to scale up laboratory data. Finally, a compacted hair pad has been suggested for use in the column, and some prospective future applications have been proposed.
