甚麼都不用做,鉛有機會自行分解。
1)
Thorium series A = 4n
212 212
Pb --> Bi + β 半衰期:10.64h 0.58MeV
82 83
212 208
Bi --> Pb + α + β
83 82
2)
Neptunium series A = 4n + 1
209 209
Pb --> Bi + β 半衰期:3.3h 0.64MeV
82 83
3)
Uranium series A = 4n + 2
214 214
Pb --> Bi + β 半衰期:26.8min 1.03MeV
82 83
212 210
Bi --> Pb + α + β
83 82
210 210
Pb --> Bi + β
82 83
210 206
Bi --> Tl + α
83 81
206 206
Tl --> Pb + β
81 82
4)
Actinium series A = 4n + 3
211 211
Pb --> Bi + β 半衰期:36.1min 1.36MeV
82 83
211 207
Bi --> Tl + α 半衰期:2.16min 6.62MeV
83 81
207 207
Tl --> Pb + β 半衰期:4.79min 1.44MeV
81 82

鉛是一個元素,不可以分解成較簡單的物質。
若果是要分解某個鉛的化合物,則視乎該化合物是甚麼物質而定。

用電解鉛礦物,不過分解過程會辭出有害物
