Membraneless Purification of Heavy Metal Contaminated Water by Ion Concentration Polarization

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.

متن کاملRemoving Copper from Contaminated Water Using Activated Carbon Sorbent by Continuous Flow
Introduction: A major concern of human being is accumulation and toxicity of heavy metals in their body. Copper is a heavy metal ion that in concentration of 2 mg/l can cause numerous complications. Different treatment methods have been proposed for removing metals from contaminated water by researchers. Among these methods, sorption seems a better method with high removal efficiency. In this s...
