95% of how much?

Edit: 95% in how much water?

From the article

"At this point, Liu and his colleagues have only tested out the method on two types of PFA—known as perfluorooctanoic acid (PFOA) and ​perfluorooctanesulfonic acid (PFOS)—in small volumes of tap water, measuring about two cups. However, the results were very promising: The effect of the hydrogen “increased the degradation of PFOA from 10% to 95%,” according to the study, “with 95% degradation achieved within 45-min treatment” at room temperature."

Has to be a misleading title. 95% of toxic chemicals in what enclosure? The entire globe or a test vial? This sounds too extreme to be in a large scale yet.

This was indeed a test: the volume of water was about two cups of water (a bit less than 500mL). The article does not say what the concentration of the chemicals in that water was.

However, it does sound like it can be applied on a larger scale fairly easily.

>“The advantage of this technology is that it is very sustainable,” Liu said. He noted that hydrogen that is introduced into contaminated sources during the process becomes harmless water at the end of the reaction. 

>At this point, the system is still in an early phase of research, but the team hopes to eventually develop it into a commercially viable machine that could zap PFAS compounds out of large water tanks, and other sources.  

>“The hydrogen-based polarization technique may be readily applied to other water ionization systems to enhance reductive destruction of PFAS and other contaminants,” the researchers concluded in the study.

I still think the NaOH in organic solvent method for 24 hours is better.

This just in: forever chemicals are cool again.

Chemical industry lobbies probably

This is probably going to be a great addition to a household's water processing system.
