Leaching of Ag in solution from the 70 : 30 SiverSil xerogel measured in different washing cycles via ICP‐AES.

Washing cycle	Ag concentration [ppm]	Amount of Ag leached [mmol]	Ag leaching [%]a
1	0.256	4.75 ⋅ 10−5	0.15
2	0.486	9.01 ⋅ 10−5	0.28
3	0.174	3.23 ⋅ 10−5	0.10
4	0.468	8.68 ⋅ 10−5	0.27
5	1.176	54.5 ⋅ 10−5	1.68
6	0.516	4.78 ⋅ 10−5	0.15
7	0.386	3.58 ⋅ 10−5	0.11
