伏安极谱法测定盐水中的总砷

Arsenic:
Electrolyte: HCl, 30%
AE: Pt (special intermediate electrolyte vessel required)
RE: Ag/AgCl/KCl 3M
Parameters: DPASV (+50 mV), special Au-RDE
Umeas = 1200 mV (60s), Umeas = 200 mV (10s),
Umeas = 200 mV (15s) without stirring, Ustart = 200 mV,
Uend = + 300 mV
Ep (As) = + 150 mV
