Of course, many of them saw such PCBs. I decided to check the content of precious metals in an elementary simple way, through ammonia, because. through ammonia, the purest palladium is obtained. I have shown this method earlier, since it is the same method as with ammonium chloride .. But in this case, when the solution contains a high content of palladium, a lot of ammonium chloride would be required - therefore, its use here is not advisable .. Besides but in this master alloy there are no base metals, except for tin. Tin will be "disposed of" completely unnecessarily, because it does not interfere with processing!
