چکیده

ABSTRACT The lethal threats to human health from heavy metals are associated with untreated ground water. We developed a high throughput single step heavy metal purification process based on Ion Concentration Polarization mechanism. Instead of microfluidic channel networks, the plastic prototype made of plastic meshes and Nafion nanoporous material was built so that the manufacturability and cost efficiency were maximized. Modeled heavy metal contaminated water was filtered below the safe concentration. Based on the demonstration, one can expect to achieve a 100mL/min throughput from a 2.5inch portable system which is capable of desalting seawater, purifying heavy metals and disinfecting biological contaminants.

Applications on agricultural and forest waste adsorbents for the removal of lead (II) from contaminated waters

At present, there is growing interest in using low cost, commercially available materials for the adsorption of heavy metals. The major advantages of adsorption technologies are its effectiveness in reducing the concentration of heavy metal ions to very low levels and the use of inexpensive adsorbent materials. In this review, agricultural and forest waste adsorbents were used to remove Pb ions...
