Hi guys
I am interested in drinking water quality testing and most drinking water test kits are not accurate.
They give positive readings on concentrated samples like sewage and not for trace elements in drinking water.
So I wanted to try out this interesting Chinese? gadget.
Search you tube for..?Water Electrolyzer (Quality Tester). The Most Dangerous Appliance Ever?
Negative comments being dangerous? and a scam.
I checked it out
There are 2 pairs of electrodes
A shiny aluminium and a dull? iron pair.
Repeated usage caused the? iron to rust.
Aluminium was confirmed? by exclusion being shiny,light,cheap and nondescript.
My drinking water? sample is RO? waste water .
This discharged RO waste water is about 4 times more concentrated than my tap water depending on machine cycling.
Concentrated means more residue better than plain tap water for analysis.
My 14 in 1test kit was basically negative? for heavy metals.
I tested this RO concentrated with this Chinese toy.
It produced a brownish residue as expected.
Collected it and allowed it dry on cap and a tissue.
This cap/tissue was analyzed with Xrf with Am241/Si pin detector.
True enough like the you tubers described there is Fe from galvanic reactions.
There appears to be Pb peak as well
I need to repeat this test with a thicker sample? to confirm .
