Episode 403 - Taking pollutants out of our water, factories and environment

How can we take pollutants easily out of our water, factories and environment? PFAS contamination is difficult to clear up, but a new method could attract, trap and destroy it with electrodes. PFAS can be found in many things, but taking it out of an area has often been very difficult. Using a tunenable electrode, in 3 hours you could extract and destroy PFAS in contaminated water. A combined clay and glass filter could neatly trap and extract CO2 from a gassy mixture. industrial processes often produce CO2 amongst other gases, but how can you quickly only separate out that CO2, reuse it and prevent it from being emitted? Lead in drinking water is a serious issue,but understanding the amount of exposure is difficult. A new method for analysing lead in drinking water tips acid onto 'filled' filters.
