The CNT is infused with chloride and when the cartridge is dipped in lead-contaminated water, the lead and chloride react to form lead chloride
molecules in the CNT.
Scientists from the Louvre Museum and the CNRS Research Institute used an electrode which was one-tenth the thickness of a human hair to look at the effect lead chloride
salt synthesised by Egyptians had on a single cell.
The research was carried out using a tiny electrode, the 10th of the size of a hair, to look at the effect of a lead chloride
synthesised by the Egyptians (laurionite) on a single cell.

Lead acetate reacts with ferric chloride to produce insoluble white lead chloride
The pregnant solution is cooled to crystallize lead chloride, followed by precipitation of the remaining metals by scrap iron.
The first step of metal recovery is to cool the pregnant solution to drop out most of the lead chloride while the other metals remain in solution.
This is also an order of magnitude lower solubility than basic lead chloride, the most common reaction product of stabilization with lead oxides.
Stabilization with dibasic lead phthalate provides slightly better retention of volume resistivity, as shown in figure 1, probably because of the lower water solubility of dichlorodibasic lead phthalate as compared to basic lead chloride.
AoBut Aowhether or not the manufacture of these lead chlorides
was deliberately connected to preventive health care by Egyptians,Ao the researchers wrote, Aoit is clear that such intentional production remains the first known example of a large scale chemic process.
