Capturing heavy metals from water

Highly magnetic carbon coated Fe-based core TurboBeads were functionlized by Koehler et al. with ethylenediaminetatraacetic acid (EDTA) similar chelator groups (DTPA). These chelating agents are known for their excelent binding properties to heavy metals. Here, the performance of functionalized TurboBeads to extract Cu, Cd and Pb from aqueous solutions was investigated at various initial concentrations from 1 ppb to 100 ppm.
