EFFECTIVE REMOVAL OF MERCURY FROM AQUEOUS STREAMS VIA ELECTROCHEMICAL ALLOY FORMATION ON PLATINUM
Tunsu, C. and B. Wickman.
Nature Communications 9:Article 4876(2018)
Filed Under: Research
Filed Under: Research
Under applied potential, Hg ions in solution form a stable PtHg4 alloy with platinum (Pt) on the cathode. A 100-nm Pt film was fully converted to a layer of PtHg4 750 nm thick. The overall removal capacity was >88 g Hg/cm3. The electrodes were easily regenerated after use. This technique allowed efficient and selective decontamination in a wide pH range for processing industrial, municipal, and natural waters. The method is suited for both high and low Hg concentrations and can reduce mercury levels far below the limits allowed in drinking water. https://www.nature.com/articles/s41467-018-07300-z
