試試這兩個(gè)方子吧,注意攪拌。
(1)Perchloric 6% + Butoxyethanol 34% + Methanol 60%,-30C, 35V, 9mA
(2) 60 mL of 60% perchloric acid + 390 mL methanol + 350 mL ethylene glycol,Voltage = 38V, t <= 15 sec, T ~ 5 C, Counter electrode = Stainless steel
Agitation: (i) gently stir electrolyte with stir bar, (ii) rapidly agitate working electrode.
Trick 1: Remove sample from electrolyte under voltage, then immediately plunge it into room-temp distilled water and agitate sample slowly.
Trick 2: Wipe working electrode with Acetone and air dry before polishing. |
