Running a pregnant AR solution through silver chloride filled filters will lose you a reasonable amount of gold. Based purely on the description of your process, you're probably better recovering initially. You can run your cpus in AP to recover the foils which will likely leave you with only gold and silver chloride.

Water filters can effectively remove lead and other contaminants from drinking water. However, this is only possible if you get a water filter with NSF certification for lead removal. There are 2 types of water filters that can remove lead; point-of-use (POU) filters and point-of-entry (POE) filters. POU lead filters remove lead from water …

Hence, these lead sulfate crystals have less reaction area and are much more difficult to be converted back during charge. Approaches to reducing sulfation include high-frequency pulse charging [23], [24], using carbon additives [25], [26] and expander components [8], [27], [28] and replacing the negative electrode with carbon [21], [29], [30].
The precipitate is filtered through a paper filter which is then ignited and completely ashed. From the weight of the sample and weight of the precipitate, the percentage of sulfate in the sample is calculated. The precipitation reaction is the following: Ba2+(aq) + SO2−4 (aq) → BaSO4(s) (1) (1) B a 2 + ( a q) + S O 4 2 − ( a q) → B a S ...

Potential Health Effects of Sulfate and Hydrogen Sulfide in Drinking Water. Sulfate Sulfate may have a laxative effect that can lead to dehydration and is of special concern for infants. With time, people become acclimated to the sulfate and the symptoms disappear. Sulfur-oxidizing bacteria pose no known human health risk. Hydrogen Sulfide
Method. Add 75 cm3 of lead nitrate and 75 cm3 potassium sulfate to a beaker. Mix the solutions with a glass rod until a precipitate forms. Put the filter paper in the funnel and place it over the conical flask. Pour the mixture from the beaker into the funnel. Use deionised water to wash any solid left in the beaker into the funnel.
One of the most important preventive measures is to ensure that the battery is always kept at a full charge. This helps to prevent the accumulation of lead sulfate crystals on the battery's plates, which can cause sulfation. Regularly charging the battery is crucial to maintaining its health and preventing sulfation.
Step 6. Turn on your battery charger. Charge your lead-acid battery for 6 hours then take a look inside the battery cells. Don't turn off your charger. If you see tiny bubbles rising to the surface in each cell, that is a good sign and means your battery cells are charging. The charging process starts to dissolve the sulfation.
Most carbon filters DO NOT remove lead or other heavy metals from drinking water. Only special activated carbon filters can handle those contaminants. Across the board, carbon is ineffective against: ... Sulfate; The best RO filters tend to use multi-stage filtration process. That way, they can utilize the good points of both activated carbon ...

So, the sulfate ions is not alone. Possibly more advantageous, further pump air/oxygen into the solution during the UV light treatment. Then per Equation [R3], expect the superoxide radical anion formation: $ce{O2 + e- = .O2- }$ which becomes, in acidic conditions, the $ce{.HO2}$ radical, which may similarly react with Lead sulfate as follows:
High concentrations of sulfate in drinking water causes a laxative effect when combined with calcium and magnesium, the two most common components of hardness. Bacteria, which attack and reduce sulfates, causes hydrogen sulfide gas (H2S) to form. Sulfate has a suggested level of 250 mg/i in the Secondary Drinking Water Standards published by ...
